Safety Information
ii
For your own safety and the safety of others, and to prevent damage to the device and
vehicles upon which it is used, it is important that the safety instructions presented
throughout this manual be read and understood by all persons operating or coming into
contact with the device.
There are various procedures, techniques, tools, and parts for servicing vehicles, as well
as in the skill of the person doing the work. Because of the vast number of test
applications and variations in the products that can be tested with this equipment, we
cannot possibly anticipate or provide advice or safety messages to cover every
circumstance. It is the automotive technician's responsibility to be knowledgeable of the
system being tested. It is crucial to use proper service methods and test procedures. It
is essential to perform tests in an appropriate and acceptable manner that does not
endanger your safety, the safety of others in the work area, the device being used, or the
vehicle being tested.
Before using the device, always refer to and follow the safety messages and applicable
test procedures provided by the manufacturer of the vehicle or equipment being tested.
Use the device only as described in this manual. Read, understand, and follow all safety
messages and instructions in this manual.
Safety Messages
Safety messages are provided to help prevent personal injury and equipment damage.
All safety messages are introduced by a signal word indicating the hazard level.
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury to the operator or to bystanders.

Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury to the operator or to bystanders.
Safety Instructions
The safety messages herein cover situations Autel is aware of. Autel cannot know,
evaluate or advise you as to all of the possible hazards. You must be certain that any
condition or service procedure encountered does not jeopardize your personal safety.
iii
DANGER
When an engine is operating, keep the service area WELL VENTILATED or attach a
building exhaust removal system to the engine exhaust system. Engines produce carbon
monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to
serious personal injury or loss of life.
It is not advised to use headphones at a high volume
Listening at high volumes for long periods of time may result in loss of hearing.
Safety Warnings
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot
engine parts.
Operate the vehicle in a well-ventilated work area, for exhaust gases are poisonous.
Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission) and make sure the parking brake is engaged.
Put blocks in front of the drive wheels and never leave the vehicle unattended while
testing.
Be extra cautious when working around the ignition coil, distributor cap, ignition wires ,
and spark plugs. These components create hazardous voltages when the engine is
running.
Keep a fire extinguisher suitable for gasoline, chemical , and electrical fires nearby.
Do not connect or disconnect any test equipment while the ignition is on or the
engine is running.
Keep the test equipment dry, clean, free from oil, water or grease. Use a mild
detergent on a clean cloth to clean the outside of the equipment as necessary.
Do not drive the vehicle and operate the test equipment at the same time. Any
distraction may cause an accident.
Refer to the service manual for the vehicle being serviced and adhere to all
diagnostic procedures and precautions. Failure to do so may result in personal injury
or damage to the test equipment.
To avoid damaging the test equipment or generating false data, make sure the
vehicle battery is fully charged and the connection to the vehicle DLC is clean and
secure.
Do not place the test equipment on the distributor of the vehicle. Strong electro-
magnetic interference can damage the equipment.

The special functions may vary among different vehicles. Follow the on-screen
instructions to complete operation.
Programming
66
Since the introduction of OBDII and leading up to modern Hybrids and EVs, hardware
and software technologies in cars have been advancing at an exponential rate. Updating
software may be the only way to fix the following issues:
Drivability
Fuel Efficiency
Power Loss
Fault Codes
Durability of Mechanical Parts
The Programming function is used to re-flash the vehicle control modules, which allows
you to update the computer software of the vehicle to the latest version, as well as to
reprogram adaptive data of certain components after making repairs or replacements.
NOTE
The programming function applies only when the
device, which serves as a PassThru interface to
transfer data to the vehicle's ECU
vehicle is connected with a VCMI
establish communication with and
Available programming operations vary by test vehicle. Only the available operations
display in the tablet menu.
There are two general types of programming operations:
A. Coding — also known as Teach-in Program, or Component Adaptation, is used to
reprogram adaptive data for vehicle control modules after repairs or replacements
of vehicle parts.
B. Reprogramming — downloads the latest version of software from the online server
database through Internet access (this procedure is done automatically when the
tablet is connected to the Internet, so there is no need to check for software updates
yourself), and reprograms the newest version into the vehicle's ECU.
NOTE
Ensure that the tablet is connected to a stable internet access before applying the ECU
programming function, so that the tablet is able to obtain access to the vehicle
manufacturer's server for update service.
Selecting the Programming function opens a menu of operation options that varies by
vehicle make and model. Selecting a menu option either displays a programming
interface or opens another menu of additional choices. Follow all screen instructions
67
while performing the programming operations. How and what information is presented
on the screen vary by the type of operation being performed.
Coding
The main section of the Coding screen displays a list of vehicle components and the
coding information that mainly consists of two parts:
1. All available systems for coding are displayed on the left side, and the coding data
or value on the right side.
2 . The bottom of the main section displays the function buttons that enable you to
manipulate the operation.
Check the vehicle condition and the coding information carefully . Use the function button
to edit Codes for the corresponding components . Tap Send when you finish editing all
items. When the operation is completed, an execution status message such as
Completed, Finished or Successful, may display.
Tap the ESC button to exit the function.
Reprogramming
Before reprogramming begins
It is mandatory that Ultra EV tablet is connected to a stable Wi-Fi network.
The tablet must be connected to the VCMI device via USB cable.
The tablet battery must be fully charged during module programming. Connect the
tablet to a charger if needed.
Attach battery maintainer to vehicle battery to ensure a steady voltage is maintained
throughout programming. Voltage requirements differ by vehicle manufacturer.
Consult vehicle manufacturer recommendations prior to programming a module.
Do not quit the application during a module reprogramming as the process may fail
and may also result in permanent damage to the module.
Typical reprogramming operations require you to input and validate VIN number first.
Tap the input box and enter the correct number. The programming interface then displays.
The main section of the reprogramming interface offers information of the hardware, the
current software version and the newest software versions to be programmed into the
control units.
A series of on- screen operational instructions will display to guide you through the
programming procedure.
68
Carefully read the on-screen information and follow the instruction to execute the
programming procedure.
Re-flash Errors
IMPORATANT
When reprogramming onboard, always make sure the vehicle battery is fully charged
and in good working condition. During reprogramming, the operation may fail if voltage
falls below the proper operation voltage. Sometimes a failed operation can be recovered ,
but the failed reprogramming can also ruin the control module. We recommend
connecting an external battery maintainer to the vehicle to ensure a steady voltage is
maintained throughout programming . The required voltage differs by vehicle
manufacturer. Consult vehicle manufacturer for correct voltage to be maintained.
Occasionally a flash update procedure may not complete properly. Common causes of
flash errors include poor cable connections between the tablet, VCMI, and vehicle, the
vehicle ignition being switched off before the flash procedure is complete, or low vehicle
battery voltage.
If the process quits, recheck all the cable connections to assure good communications
and initialize the flash procedure. The programming procedure will automatically repeat
if the previous operation does not succeed.
Diagnostic Report
Pre-Scan and Post-Scan
To perform the pre-scan and post-scan functions

Function Descriptions
This section describes the various functions of each diagnostic option:
DTC & FFD
When this function is selected, the screen displays a list of Stored Codes and Pending
Codes. When the Freeze Frame data of certain DTCs are available for viewing, a
snowflake button will display on the right side of the DTC item. The Erase Codes and
Read Codes functions can be applied by tapping the function buttons at the bottom of
the screen.
Figure 6-2 DTC & FFD Screen
Current Codes
Current codes are emission-related DTCs from the ECM of the vehicle. OBD
II/ EOBD Codes have a priority according to their emission severity, with higher-
priority codes overwriting lower-priority ones. The priority of the code determines the
illumination of the Malfunction Indicator Light (MIL) and the codes erase procedure.
Manufacturers rank codes differently, so DTCs may vary by vehicle.
86
Pending Codes
These are codes whose storing conditions have been met during the last drive cycle,
but need to be met on two or more consecutive drive cycles before the DTC stored.
The purpose of displaying pending codes is to assist the service technician after a
vehicle repair when diagnostic information is cleared, by reporting test results after
a single driving cycle.
b) If a test fails during the driving cycle, the DTC associated is reported. If the
pending fault does not occur again within 40 to 80 warm-up cycles, the fault is
automatically cleared from memory.
c) Test results reported do not necessarily indicate a faulty component or system.
If test results indicate another failure after additional driving, a DTC is stored to
indicate a faulty component or system.
Freeze Frame
In most cases the stored frame is the last DTC reported. Certain DTCs, those that
have a greater impact on vehicle emission, have a higher priority. In these cases,
DTC of the highest priority is the one for which the freeze frame records are retained.
Freeze frame data includes a "snapshot" of critical parameter values at the time the
DTC is stored.
Erase Codes
This option is used to clear all emission- related diagnostic data including DTCs,
freeze frame data and specific manufacturer-enhanced data from the vehicle ECM.
This option resets the I/M Readiness Monitor Status for all vehicle monitors to Not
Ready or Not Complete status.
A confirmation screen displays when the clear codes option is selected to prevent
accidental loss of data. Select Yes on the confirmation screen to continue, or No to
exit.
I/ M Readiness
This function is used to check the readiness of the monitoring system. It is an excellent
function to use prior to having a vehicle inspected for state emissions compliance.
Selecting I/M Readiness opens a submenu with two choices:
Since DTCs Cleared — displays the status of monitors since the last time the DTCs
are erased.
This Driving Cycle — displays the status of monitors since the beginning of the
current drive cycle.
87
Live Data
This function enables the display of real-time PID data from the ECU. Displayed data
includes analog and digital input and output, and system status information broadcast in
the vehicle data stream.
Live data can be displayed in various modes, seeLive Datafor detailed information.
O2 Sensor Monitor
This function allows retrieval and review of recent O2 sensor monitor test results stored
on the vehicle's on-board computer.
The O2 Sensor Monitor test function is not supported by vehicles that communicate using
a controller area network (CAN). For O2 Sensor Monitor tests results of CAN-equipped
vehicles, refer toOn-Board Monitor.
On- Board Monitor
This function allows you to view the results of On-Board Monitor tests. The tests are
useful after the service when a vehicle's control module memory is already erased.
Component Test
This function enables dual-directional control of the ECM so that the diagnostic tool can
transmit control commands to operate the vehicle systems. This function is useful in
determining how well the ECM responds to a command.
Vehicle Information
This function enables the display of the vehicle identification number (VIN), calibration
identification number, calibration verification number (CVN), and other information of the
test vehicle.
Vehicle Status
This function checks the current condition of the vehicle, such as the communication
protocols of OBDII modules, number of fault codes, and status of the Malfunction
Indicator Light (MIL).

service operations.
Figure 8-1 Service Menu
Several most commonly used services are described in this chapter.
Oil Reset Service
Perform reset for the Engine Oil Life system, which calculates an optimal oil life change
interval depending on the vehicle driving conditions and climate. The Oil Life Reminder
must be reset each time the oil is changed, so the system can calculate when the next
oil change is required.
103
NOTE
1. Always reset the engine oil life to 100% after every oil change.
2. All required work must be carried out before the service indicators are reset. Failure
to do so may result in incorrect service values and cause DTCs to be stored by the
relevant control module.
3 . For some vehicles, the scan tool can reset additional service lights such as
maintenance cycle and service interval. On BMW vehicles for example, service
resets include engine oil, spark plugs, front/ rear brakes, coolant, particle filter, brake
fluid, micro filter, vehicle inspection, exhaust emission inspection and vehicle checks.
Electric Parking Brake (EPB) Service
This function has a multitude of usages to maintain the electronic braking system safely
and effectively. The applications include deactivating and activating the brake control
system, assisting with brake fluid control, opening and closing brake pads, and setting
brakes after disc or pad replacement.
EPB Safety
It can be dangerous to perform Electric Parking Brake (EPB) system maintenance, so
before you begin the service work, please keep these rules in mind.
Ensure that you are fully familiar with the braking system and its operation before
commencing any work.
The EPB control system may be required to be deactivated before carrying out any
maintenance/diagnostic work on the brake system. This can be done from the tool
menu.
Only perform maintenance work when the vehicle is stationary and on level ground.
Ensure that the EPB control system is reactivated after the maintenance work has
been completed.
NOTE
Autel accepts no responsibility for any accident or injury arising from the maintenance of
the Electric Parking Brake system.
Tire Pressure Monitoring System (TPMS) Service
This function allows you to quickly look up the tire sensor IDs from the vehicle's ECU, as
well as to perform TPMS replacement and reset procedures after tire sensors are
replaced.
Battery Management System (BMS) Service
104
The Battery Management System (BMS) allows the tool to evaluate the battery charge
state, monitor the close-circuit current, register the battery replacement, activate the rest
state of the vehicle, and charge the battery via the diagnostic socket.
NOTE
1. This function is not supported by all vehicles.
2. The sub functions and actual test screens of the BMS may vary by vehicle, please
follow the on-screen instructions to make correct option selection.
The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed Glass Mat)
battery. Lead acid battery contains liquid sulphuric acid and can spill when overturned.
AGM battery (known as VRLA battery, valve regulated lead acid) also contains sulphuric
acid, but the acid is contained in glass mats between terminal plates.
It is recommended that the replacement aftermarket battery has the same specifications,
such as capacity and type, as the exiting battery. If the original battery is replaced with a
different type of battery (e.g. a lead-acid battery is replaced with an AGM battery) or a
battery with a different capacity (mAh), the vehicle may require reprogramming of the
new battery type, in addition to, performing the battery reset. Consult the vehicle manual
for additional vehicle-specific information.
Diesel Particle Filter (DPF) Service
The Diesel Particle Filter (DPF) function manages DPF regeneration, DPF component
replacement teach-in and DPF teach-in after replacing the engine control unit.
The ECM monitors driving style and selects a suitable time to employ regeneration. Cars
driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven
more with higher load and speed. In order for regeneration to take place, a prolonged
high exhaust temperature must be obtained.
In the event of the car being driven in such a way that regeneration is not possible, i.e.,
frequent short journeys, a diagnostic trouble code will eventually be registered in addition
to the DPF light and "Check Engine" indicators displaying. A service regeneration can be
requested in the workshop using the diagnostic tool.
Before performing a forced DPF regeneration using the tool, check the following items:
The fuel light is not on.
No DPF-relevant faults are stored in system.
The vehicle has the specified engine oil.
The oil for diesel is not contaminated.
105
IMPORTANT
Before diagnosing a problem vehicle and attempting to perform an emergency
regeneration, it is important to obtain a full diagnostic log and read out relevant measured
value blocks.
NOTE
1. The DPF will not regenerate if the engine management light is on, or there is a faulty
EGR valve.
2. The ECU must be re-adapted when replacing the DPF and when topping up the fuel
additive Eolys.
3. If the vehicle needs to be driven in order to perform a DPF service, a second person
is needed for the function. One person should drive the vehicle while the other
person observes the screen on the Tool. Do not attempt to drive and observe the
scan tool at the same time. This is dangerous and puts your life and the lives of other
motors and pedestrians at risk.
Immobilizer (IMMO) Service
An immobilizer is an anti-theft mechanism that prevents an automobile's engine from
starting unless the correct ignition key or other device is present. This device prevents
thieves from starting the car by a method known as hot wiring. Most new vehicles have
an immobilizer as standard equipment. An important advantage of this system is that it
doesn't require the car owner to activate it; it operates automatically. An immobilizer is
considered as providing much more effective anti-theft protection than an audible alarm
alone; many auto insurance companies offer lower rates for vehicles that are equipped
with an immobilizer.
As an anti-theft device, an immobilizer disables one of the systems needed to start a
car' s engine, usually the fuel supply or the ignition. This is accomplished by radio
frequency identification between a transponder in the ignition key and a device called a
radio frequency reader in thesteering column. When the key is placed in the ignition, the
transponder sends a signal with a unique identification code to the reader, which relays
it to a receiver in the vehicle' s computer control module. If the code is correct, the
computer allows the fuel supply and ignition systems to operate and start the car. If the
code is incorrect or absent, the computer disables the system, and the car will be unable
to start until the correct key is placed in the ignition.
The IMMO service can disable a lost vehicle key and program the replacement key fob.
One or more replacement key fobs can be programmed.
Steering Angle Sensor (SAS) Service
106
Steering Angle Sensor Calibration permanently stores the current steering wheel position
as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front
wheels and the steering wheel must be set exactly to the straight-ahead position before
calibration. In addition, the vehicle identification number ( VIN) is also read from the
instrument cluster and stored permanently in the steering angle sensor EEPROM. On
successful completion of calibration, the steering angle sensor fault memory is
automatically cleared.
Calibration must always be carried out after the following operations:
Steering wheel replacement
Steering angle sensor replacement
Any maintenance that involves opening the connector hub from the steering angle
sensor to the column
Any maintenance or repair work on the steering linkage, steering gear or other
related mechanism
Wheel alignment or wheel track adjustment
Accident repairs where damage to the steering angle sensor or assembly, or any
part of the steering system may have occurred
NOTE
1. Autel accepts no responsibility for any accident or injury arising from servicing the
SAS system. When interpreting DTCs retrieved from the vehicle, always follow the
manufacturer's recommendation for repair.
2. All software screens shown in this manual are examples, actual test screens may
vary by test vehicle. Pay attention to the menu titles and onscreen instructions to
make correct option selections.
3. Before starting procedure, make sure vehicle has an ESC button. Look for button on
dash.

Measurement
The Measurement application can provide all the features needed for performing
electrical and electronic circuit tests as well as monitoring signal activities on today's
vehicles.
After properly connecting with a test vehicle and communicating with MaxiSys Ultra
EV, the VCMI (Vehicle Communication and Measurement Interface) is used as an
integrated device that functions as an oscilloscope, a waveform generator, a
multimeter and a bus inspection.
Oscilloscope
An oscilloscope is a measuring instrument that shows how a signal varies with time
in a graphical way. Various signal activities can be displayed and monitored on a
two-dimensional grid. The graphical form created by a signal is called a waveform.
The voltage-time characteristic of the signal or waveform is drawn as a visual line
called the trace.

9 protocols are available: CAN High, CAN Low, LIN, FlexRay, RS232/UART, I2S,
I2C, USB (1.0/1.1), and CAN FD. The detailed setting options vary according to each
protocol.
CAN High / CAN Low: Controller Area Network (CAN) is a serial protocol used
in automotive to allow microcontrollers to communicate with each other. It
typically uses differential signaling ( with signals named CAN High and CAN
Low) to increase noise immunity.
LIN: Local Interconnect Network (LIN) is a serial protocol used in automotive
electronics to allow microcontrollers to communicate with low-speed
peripherals.
FlexRay: It is an automotive network communications protocol for high-speed
data.
RS232/UART: Universal Asynchronous Receiver/Transmitter (UART) is the
communication interface found in the serial or COM ports once commonly
found on computers. Each channel of data is transmitted on a single wire pair
using an electrical standard such as RS232.
139
I2S: Inter-IC Sound (I2S) is a serial protocol used in digital audio devices for
communications between circuits such as CD transports and audio DACs.
I2C: Inter-Integrated Circuit (I2C) is a way to connect peripheral chips in
consumer electronics products and is widely used in embedded systems.
USB (1.0/1.1): Universal Serial Bus (USB) is widely used in personal
computers and tablets for communication.
CAN FD: The CAN FD serial protocol is an extended version of the Controller
Area Network (CAN), which allows electronic controllers to receive sensor
messages and transmits control messages faster than traditional CAN
communication.
Baud Rate: The baud rate will display a default value, which needs to be manually
set according to the actual signal to get the correct decoding result.
Threshold: The voltage that defines the transition in either direction between high
logic state and low logic state.
Name: The name of the protocol that you have selected above. The channel and the

Auto Scale
Use the Auto Scale button to trigger the device to automatically analyze the signal
of the opened channel, and automatically set the appropriate amplitude and time
base range to display the signal correctly. In auto scale setting, the time base is only
valid for periodic signals.
Main View Section
Up to four traces, along with digital readouts of current signal values, signal status
and triggering conditions, can be displayed simultaneously on the main view section
screen.
Each trace has two control features , X-axis and Y-axis, which enable you to adjust
the oscilloscope settings to suit the particular test measurement. If multiple traces
are displayed at the same time, the Y-axis for each trace is adjusted separately while
the X-axis is the same for all traces.
Y-axis — the voltage level is recorded on the vertical. It displays on the left side of
the screen.
X-axis — time is presented on the horizontal line. It is shown along the bottom of
the screen.
Measurement Overrange Indicator
When the amplitude exceeds the measurement input range, a red overrange
indicator with the message "overrange" is displayed in the top left corner of the
146
screen. Exceeding the common-mode input range may result in inaccurate
measurements and can lead to severe signal distortion.

Description
None
In this trigger mode, the oscilloscope can continuously capture
data, without waiting for a trigger event.
Auto
In this trigger mode, the oscilloscope will wait for a trigger before
capturing data. It can automatically update after a short period,
even if the signal does not across the trigger point.
Repeat
In this trigger mode, the oscilloscope waits until a trigger event
occurs. If there is no trigger event, nothing will be displayed on
the screen.
Single
In this trigger mode, the oscilloscope stops capturing data once
a trigger event occurs.
Channel
Select the applicable trigger channel from the dropdown menu. The selected channel
is the one that the oscilloscope monitors for the trigger condition.
Pulse Direction
Two pulse direction settings are available: Rise and Fall.
166
Rise Edge Trigger — Indicates trigger is turned on to start the trace on the
rising edge of the waveform.
Fall Edge Trigger — Indicates trigger is turned on to start the trace on the
falling edge of the waveform
Threshold
The Threshold allows you to set the voltage threshold for the trigger.
To precisely position the trigger point, input the value in the Threshold field in
the trigger settings dialog box.
To roughly position the trigger point, drag the trigger point to a desired position.
To configure the trigger settings

Window Pulse Width
This trigger type combines with the window trigger and the pulse width trigger. It
detects when a signal enters or exits an input range and stays for a specified period
of time. Two Region options can be selected: In range and Out of range.
Horizontal Distortion
This trigger type can be monitored when the signal goes high or low for longer than
the specified time.
Window Distortion
This trigger type monitors when a signal enters a specified voltage range and stays
within that range for a specified period of time.
Underthrow
This trigger type monitors a pulse that exceeds one threshold and then drops below
the threshold without exceeding the second threshold. This type of trigger is typically

Troubleshooting
A. If the oscilloscope cannot communicate with the MaxiSys Tablet:
Ensure the VCMI device is properly connected to the MaxiSys Tablet via BT,
Wi-Fi or with the supplied USB cable.
Restart the MaxiSys Tablet and reconnect the VCMI device if communication
between the two continues to fail .
B. If unwanted signals are displayed or signals are distorted:
Use only the supplied test leads or probes to connect with the input channels.
Check the test leads or probes for damage.
Ensure the polarity of the test leads connections are correct.
Ensure the signal and ground connections are clean and secure.
Ensure the ground lead is providing a direct ground from the circuit to the input
channel.
Isolate the test leads from other components, leads, or systems that may induct
unwanted noise into the signal being tested including the electric motors,
178
secondary ignition components, relays, alternators .
Glossary
AC/ DC Control
Each channel can be set to either AC coupling or DC coupling. With DC coupling,
the voltage displayed onscreen is equal to the true voltage of the signal with respect
to ground. With AC coupling, any DC component of the signal is filtered out, leaving
only the variations in the signal for the AC component.
Aliasing
When the signal frequency gets higher than half the scope's maximum sampling rate
and exceeds the limit, a distorted waveform displays. This distortion is called aliasing.
Amplitude
The maximum voltage generated from the zero volts line of the oscilloscope.
Analog Bandwidth
The frequency at which a displayed sine wave has half the power of the input sine
wave (about 71% of the amplitude).
Buffer Size/ Cache Size
The size of the oscilloscope's buffer memory. The buffer memory is used by the
oscilloscope to temporarily store data. This helps to compensate for the differences
in data transfer rate from one device to another.
Frequency
The number of signal occurrences per second. Frequency is measured in Hz (hertz).
Peak to peak voltage
The difference in voltage between the minimum and maximum voltages occurring in
the waveform.
Time Base
The time interval across the scope display.
179
Voltage Range
The range between the maximum and minimum voltages that can be accurately
captured by the oscilloscope.
Sampling Rate
The number of samples per second captured by the oscilloscope. The faster the
sampling rate of the scope, the more frequently it measures the signal voltage, and
so the more detailed will be the trace that appears on the scope screen.
Multimeter
180
The multimeter is a multi-function and multi-range measuring instrument. When the
VCMI (Vehicle Communication and Measurement Interface) device is connected

About Battery Usage
Your tablet is powered by a built-in lithium-ion polymer battery, which enables you to
recharge your battery when there is electricity left .
DANGER
The built-in Lithium-ion Polymer battery is factory replaceable only; incorrect replacement
or tampering with the battery pack may cause an explosion.
Do not use a damaged battery charger.
Do not disassemble or open crush, bend, deform, puncture or shred.
Do not modify, remanufacture or attempt to insert foreign objects into the battery, or
expose the battery to fire, explosion or another hazards.
Only use the specified charger and USB cables. Failure to use Autel-authorized
charger and/or USB cables, may result in device malfunction or failure.
Use of an unqualified battery or charger may present a risk of fire, explosion, leakage,
or another hazards.
Avoid dropping the tablet. If the tablet is dropped, especially on a hard surface, and
you suspect damage, take the tablet to a service center for inspection.
310
Try to keep closer to your wireless router to reduce battery usage .
The time needed to recharge the battery varies depending on the remaining battery
capacity.
Battery life inevitably shortens over time.
Unplug the charger once the tablet is fully charged since overcharging may shorten
battery life.
Keep the battery in temperate environments. Do not place it inside a car when it is
too hot or too cold, which may reduce the capacity and life of the battery .

Compliance Information
FCC Compliance FCC ID: WQ8MAXISYSULTRA
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
SAR
The radiated output power of this device is below the FCC radio frequency exposure
limits. Nevertheless, the device should be used in such a manner that the potential for
human contact is minimized during normal operation.
The exposure standard for wireless devices employs a unit of measurement known as
the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/Kg. Tests
for SAR are conducted using standard operating positions accepted by the FCC with the
314
device transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the actual SAR level
of the device while operating can be well below the maximum value. This is because the
device is designed to operate at multiple power levels so as to use only the power
required to reach the network. To avoid the possibility of exceeding the FCC radio
frequency exposure limits, human proximity to antenna should be minimized.
