Note: To avoid permanent damage, please take note of the battery
polarity before inserting the batteries.
Note:Lithium batteries are recommended for cold weather
environments.
1. Open the battery compartment as shown below. Insert two fresh AAA
batteries(with the negative terminal of the battery in contact with each
spring).
2. The LED shown in Figure 1 will light up (visible through the plastic).
Figure 1
3.
It is recommended you mount the thermo-hygrometer sensor outside in
a shaded area. A north facing wall is preferred because it is in the shade
most of the day. Direct sunlight and radiant heat sources will result in
inaccurate temperature readings. Although the sensor is not waterproof, it
is best to mount in a well protected area, such as under an eve.

2.2 Display Console
1.Power on with adapter to keep the backlight on. The battery is a back-up
option, saving console settings when powered off from adaptor.
Note: Power the console with an adapter first, not the batteries,
otherwise the backlight will not light on constantly.
2. Remove the battery door on the back of the display, install 3xAAA
batteries and close the door, place on the desk or mount on the wall.

3.1 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and
metal barriers. We recommend the following best practices for trouble free
wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet
away from computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz
devices and communication is intermittent, try turning off these other
devices for troubleshooting purposes. You may need to relocate the
transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300 feet(100m) line of sight
(no interference, barriers or walls) but typically you will get 100 feet(30m)
maximum under most real-world installations, which include passing
through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers
such as aluminum siding. If you have metal siding, align the remote and
console through a window to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium.
Each “wall”or obstruction decreases the transmission range by the factor
shown below.

4. Low Battery Icon
A low battery indicator icon is shown in the display window for
thermo-hygrometer sensor. When the low battery icon appears (the battery
voltage is lower than 2.4V), replace the batteries in the sensor with fresh
batteries. Be sure to never mix old and new batteries, and never mix
battery types such as alkaline and lithium together.
4.1 Comfort Icon
The comfort icon is based on humidity ranges specified in Figure 5. The
icon is displayed for indoor humidity.

Figure 5
4.2 Rate of Change Icon
The rate of change icon detects rapid changes in temperature and
humidity.
If the arrow points upward, the temperature is increasing at a rate of +2°F
per 30 minutes (or greater). If the arrow points downward, the temperature
is decreasing at a rate of -2°F per 30 minutes (or less).
If the arrow points upward, the humidity is increasing at a rate of +5% per
30 minutes (or greater). If the arrow points downward, the humidity is
decreasing at a rate of -5% per 30 minutes (or less).
5. Radio Controlled Clock (RCC)
After the console is powered up, it starts synchronizing with remote sensor
for 3 minutes, and then the console starts radio controlled clock (RCC)
reception. During the RCC reception period (maximum 10 minutes), no
weather data is transmitted to avoid interference.
If RCC is not successfully received within 10 minutes, RCC reception
process will stop temporarily and automatically resume every one hour
until the signal is successfully captured. The regular communication
between indoor console and remote sensor will resume once RCC
7
reception process is finished. In some locations, RCC reception may take a
couple of days to receive the signal.
6. Display Console Features

7. Adjustment or Calibration
Note: The calibrated value can only be adjusted on the console.
Note: The measured humidity range is between 10 and 99%. Humidity
cannot be accurately measured outside of this range. Thus, the humidity
cannot be calibrated below 10% or above 99%.
The purpose of calibration is to fine tune or correct for any sensor error
associated with the devices margin of error. The measurement can be
adjusted from the console to calibrate to a known source.
Calibration is only useful if you have a known calibrated source you can
compare it against, and is optional. This section discusses practices,
procedures and sources for sensor calibration to reduce manufacturing
and degradation errors. Do not compare your readings obtained from
sources such as the internet, radio, television or newspapers. They are in a
different location and typically update once per hour.
The purpose of your weather station is to measure conditions of your
surroundings, which vary significantly from location to location.
7.1 Temperature Calibration
In normal mode, press and hold the SET/MODE and CHANNEL/+ keys at
the same time for five seconds to enter the temperature calibration mode.
The indoor temperature will begin flashing.
Press the [+] or [-] key to increase or decrease the temperature reading (in
increments of 0.1). Press and hold the [+] or [-] key for three seconds to
increase or decrease rapidly.
15
Press the ALARM key to reset current value.
Press the SET/MODE key switch to sensor temperature calibrated mode.
Press the SET/MODE key switch to exit calibrated mode.To exit the
calibration mode at any time, press the SNOOZE button on the right side of
the display console. If no operation is performed, the calibration mode will
timeout in 30 seconds.
7.2 Humidity Calibration
In normal mode, press and hold the SET/MODE and HISTORY/- keys at
the same time for five seconds to enter the humidity calibration mode. The
indoor humidity will begin flashing.
Press the [+] or [-] key to increase or decrease the humidity reading (in
increments of 1%). Press and hold the [+] or [-] key for three seconds to
increase or decrease rapidly.
Press the ALARM key to reset current value.
Press the SET/MODE key switch to sensor humidity calibrated mode.
Press the SET/MODE key switch to exit calibrated mode.To exit the
calibration mode at any time, press the SNOOZE button on the right side of
the display console. If no operation is performed, the calibration mode will
timeout in 30 seconds.
Note: Humidity is a difficult parameter to measure accurately and drifts
over time. The calibration feature allows you to zero out this error. To
calibrate humidity, you will need an accurate source, such as a sling
psychrometer or Humidipaks One Step Calibration kit.
7.3 Pressure Calibration
In normal mode, press and hold the SET/MODE and ALARM keys at the
same time for five seconds to enter the pressure calibration mode. The
ABS of pressure will begin flashing.
Press the [+] or [-] key to increase or decrease the pressure reading.
Press and hold the [+] or [-] key for three seconds to increase or decrease
rapidly.
Press the ALARM key to reset current value.
Press the SET/MODE key switch to REL of pressure calibrated mode.
Press the SET/MODE key switch to exit calibrated mode. To exit the
calibration mode at any time, press the SNOOZE button on the right side of
16
the display console. If no operation is performed, the calibration mode will
timeout in 30 seconds.
1. Absolute Pressure Calibration
Press the SET/MODE key again to enter the pressure calibration mode.
Press the [+] or [-] key to increase or decrease the pressure reading (in
increments of 0.00 inHg))
2. Relative Pressure Calibration
In the calibration mode, press the SET/MODE button again, the “REL”
symbol will display at the pressure section, the relative pressure value will
flash. (The default value is 0.00 inHg)
Press the [+] or [-] key to increase or decrease the relative pressure value
(in increments of 0.01 inHg).
Press and hold the [+] or [-] for three seconds to increase or decrease
rapidly.
Press the ALARM key to reset current value.
Example: The calibrated pressure sources measure 25.00
inHg. The display console pressure reads 24.85 inHg.
Offset = 25.00 - 24.85 = 0.15 inHg
Note: The display console displays two different pressures: absolute
(measured) and relative (corrected to sea-level).
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the air
pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be as if located at sea-level) is
generally higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude
of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013.2hpa). This is the
average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013.2hpa) are considered high
17
pressure and relative pressure measurements less than 29.92 inHg are
considered low pressure.
To determine the relative pressure for your location, locate an official
reporting station near from you (the internet is the best source for real-time
barometer conditions, such as the website of Weather.com or
Wunderground.com), and set your weather station to match the official
reporting station.
8. Alarm Mode

9. Other Console Features
The following section describes additional features and display icons.
9.1 Weather Forecasting
Note: The weather forecast or pressure tendency is based on the rate of
19
change of barometric pressure. In general, when the pressure increases,
the weather improves (sunny to partly cloudy) and when the pressure
decreases, the weather degrades (cloudy to rain).
The weather forecast is an estimation or generalization of weather
changes in the next 24 to 48 hours, and varies from location to location.
The tendency is simply a tool for projecting weather conditions and is
never to be relied upon as an accurate method to predict the weather.

10. Glossary of Terms
Term
Definition
Accuracy
Accuracy is defined as the ability of a measurement to
match the actual value of the quantity being measured.
Hygrometer
A hygrometer is a device that measures relative
humidity. Relative humidity is a term used to describe
the amount or percentage of water vapor that exists in
air.
Range
Range is defined as the amount or extent a value can
be measured.
Resolution
Resolution is defined as the number of significant digits
(decimal places) to which a value is being reliably
measured.
21
Term
Definition
Absolute
Barometric
Pressure
Relative barometric pressure, corrected to sea-level. To
compare pressure conditions from one location to
another, meteorologists correct
pressure to sea-level conditions. Because the air
pressure decreases as you rise in altitude, the sea-level
corrected pressure (the pressure your location would be
at if located at sea-level) is generally higher than your
measured pressure.
Relative
Barometric
Pressure
Measured barometric pressure relative to your location
or ambient conditions.
HectoPascals
(hPa)
Pressure units in SI (international system) units of
measurement. Same as millibars (1 hPa = 1 mbar)
Inches of
Mercury (inHg)
Pressure in Imperial units of measure.
1 inch of mercury = 33.86 millibars

1. Clean the Thermo-hygrometer once every 3 months
2. Replace the thermo-hygrometer transmitter batteries once every 3
months.
Battery life: Batteries
in
base
stations
with
good
reception will last
at least 3 months.
Intermittent reception may shorten battery life.
(Use lithium batteries in cold climates below -20 °C).
13. Troubleshooting Guide
.
If the sensor communication is lost, dashes
(--.-) will be displayed on the screen. To
reacquire the signal, press and hold the
CHANNEL/+ button for 3 seconds, the remote
search icon will be constantly displayed.
Once the signal is reacquired, the remote
search icon will turn off, and the current
values will be displayed.
The maximum line of sight communication
range is 300ft and 100ft under most conditions.
Move the sensor assembly closer to the
display console.
23
Problem
Solution
If the sensor assembly is too close (less than
5ft), move the sensor assembly away from the
display console.
Make sure the remote sensor LCD display is
working and the transmitter light is flashing
once per 60 seconds.
Install a fresh set of batteries in the remote
thermo-hygrometer. For cold weather
environments, install lithium batteries.
Make sure the remote sensors are not
transmitting through solid metal (acts as an RF
shield), or earth barrier (down a hill).
Move the display console around electrical
noise generating devices, such as computers,
TVs and other wireless transmitters or
receivers.
Move the remote sensor to a higher location.
Move the remote sensor to a closer location.
Temperature sensor
reads too high in the
day time.
Make sure the thermo-hygrometer is mounted
in a shaded area. The pre preferred location is
a north facing wall because it is in the shade
most of the day.
Indoor and Outdoor
Temperature do not
agree
Allow up to one hour for the sensors to
stabilize due to signal filtering. The indoor and
outdoor temperature sensors should agree
within 4 °F (the sensor accuracy is ± 2 °F).
Use the calibration feature to match the indoor
and outdoor temperature to a known source.
Indoor and Outdoor
Humidity do not agree
Allow up to one hour for the sensors to
stabilize due to signal filtering. The indoor and
24
Problem
Solution
outdoor humidity sensors should agree within
10 % (the sensor accuracy is ± 5 %).
Use the calibration feature to match the indoor
and outdoor humidity to a known source.
Display console contrast
is weak
Replace console batteries with a fresh set of
batteries.
The atomic clock signal
is weak or no signal
A minimum distance of 8feet to all sources of
Interference , such as televisions or computer
monitors.
Radio reception is weaker in rooms with
concrete walls (e.g.: in cellars) and in offices.
In such circumstances, place the device close
to the window .
The atomic signal is
strong but the wrong
time
Make sure your time zone is set correctly.
Signal reception is normally better at night and
when the weather is clear. The atomic signal
generally takes 2~5 days to synchronize, so it
is important to manually set the time and date
after powering on the display.
Do not set the time or
date, and alarm
While in Normal Mode, press and hold the
SET/MODE key for at least three seconds to
enter the Set Mode.
While in Normal Mode, press and hold the
ALARM key for three seconds to enter the
alarm mode, Then press and hold the
SET/MODE key for three seconds. The alarm
parameter will begin flashing.
The wrong day of the
week displayed
Please make sure that the year, month, and
day are all set correctly.
Do not sound for both
alarms and key strokes
In normal mode, press and hold the
HISTORY/- key for three seconds to turn the
beeper on.
