3.Turn o the radio power when charging. Using the radio while charging may
inteere with proper batte charging.
4.Avoid disconnecting the power source or batte during the charging
process, as this may disrupt the charging procedure.
5.If the usable time is signicantly reduced even after a full charge, the
batte has reached the end of its life and should be replaced.
6.Do not disconnect and reconnect a fully charged batte for recharging, as
this may shoen batte life or cause damage.
7.Do not charge the batte or radio when they are wet. Before charging, d
them with a cloth to avoid hazards.
8.Eliminating the Risk, keep away from the ammable materials,heat sources
and ignition sources while a batte is charged. Charging should only take
place in a well ventilated area and when someone is about to be aware and
react to a potential issue.
9.To reduce risk of re, a batte should not be charged for more than 8 hours
and disconnect charger from line voltage (AC outlet) by removing main plug
even if the batter is not completely charged.Don't leave a device unattended
while charging. Disconnect the charger when the device is fully charged: do
not overcharge the device.
Charging Procedure
Note: Turn o the radio while charging.
1.Desktop Charger: Inse the radio with the batte attached into the desk-
top charger, ensuring good contact between the batte contacts and the
charger contacts. The charger's red indicator light will illuminate steadily,
indicating charging is in progress. When the red light turns o and the green
light illuminates, the batte is fully charged. Unplug the charger from the
outlet and remove the batte.

Disposal information
The crossed-out wheeled-bin symbol on your product, literature,
or packaging reminds you that all electrical and electronic
products, batteries, or accumulators must be taken to designated
collection locations at the end of their working life. Do not
dispose of these products as unsoed municipal waste.Remove
and immediately recycle or dispose of used batteries according to
local regulations and keep away from children. Do NOT dispose of batteries in
household trash or incinerate.
RF Exposure Safety
This two-way radio uses electromagnetic energy in the radio frequency (RF)
spectrum to provide communications between two or more users over a
distance. RF energy, which when used improperly, can cause biological
damage. Please refer to the following websites for more information on what
RF energy exposure is and how to control your exposure to assure compli-
ance with established RF exposure limits: http://www.who.int/en/
Transmit no more than the rated duty factor 50% of the time. Transmitting
necessa information or less, is impoant because the radio generates
measurable RF energy exposure only when transmitting in terms of measur-
ing for standards compliance. For users who wish to fuher reduce their
exposure, some eective measures to reduce RF exposure include:
- Reduce the amount of time spent using your wireless device.
- Use a speakerphone, earpiece, headset, or other hands-free accessory to
reduce proximity to the head (and thus head exposure). While wired earpiec-
es may conduct some energy to the head and wireless earpieces also emit a
small amount of RF energy, both wired and wireless earpieces remove the
greatest source of RF energy (handheld device) from proximity to the head
and thus can greatly reduce total exposure to the head.
- Increase the distance between wireless devices and your body.
This radio is designed for and classified as "General population/uncontrolleduse". General
population/uncontrolled environments are defined as locationswhere there is exposure of
individuals who have no knowledge or control ofRF exposure level.
Hand-held Mode
To control your exposure and ensure compliance with the
controlled environment exposure limits, always adhere to
the following procedure:
- To receive calls, release the PTT button.
- To transmit (talk), press the Push-to-Talk (PTT) button in front of the face.
11
background
- Hold the radio in a veical position with the microphone (and other pas of
the radio including the antenna) at least one inch (2.5 centimeters) away from
the nose or lips.
Electromagnetic Inteerence/Compatibility
Nearly eve electronic device is susceptible to electromagnetic inteerence
(EMI) if inadequately shielded, designed, or otherwise congured for electro-
magnetic compatibility. During transmissions, your radio generates RF energy
that can possibly cause inteerence with other devices or systems. To avoid
such inteerence, turn o the radio in areas where signs are posted to do so,
such as hospitals or healthcare facilities.
Persons with pacemakers, implantable cardioveer debrillators (ICDs) or
other active implantable medical devices should:
• Consult with their physicians regarding the potential risk of inteerence
from radio frequency transmitters, such as poable radios (poorly shielded
medical devices may be more susceptible to inteerence).
Turn the radio OFF immediately if there is any reason to suspect that
inteerence is taking place.
• Do not car the radio in a chest pocket or near the implantation site, and
car or use the radio on the opposite side of the body from the implantable
device to minimize the potential for inteerence.
Hearing Aids: Some digital wireless radios may inteere with some hearing
aids. In the event of such inteerence, you may want to consult your hearing
aid manufacturer to discuss alternatives.
Other Medical Devices: If you use any other personal medical device, consult
the manufacturer of your device to determine if it is adequately shielded from
RF energy. Your physician may be able to assist you in obtaining this informa-
tion.
Turn o your radio in the following conditions:
Turn o your radio prior to entering any area with a potentially hazardous or
explosive atmosphere. Only radio types that are especially qualied should be
used in such areas as “Intrinsically Safe”.
Note: the areas with potentially explosive atmosphere referred to above
include blasting caps, blasting areas, inammable gas, dust paicles, metallic
powders, grain powders, fueling areas such as below decks on boats, fuel or
chemical transfer or storage facilities, areas where the air contains chemicals
or paicles (such as grain, dust or metal powders) and any other area where
you would normally be advised to turn o your vehicle engine. Areas with
potentially explosive atmospheres are often – but not always posted.
Use of Communication Devices While Driving
•Always check the laws and regulations on the use of radios
in the areas where you drive. Use of Communication Devices,
for example, mobile radio, may not be allowed.
• Give full attention to driving and to the road.
• Use hands-free operation, if available.
• Pull o the road and park before making or answering a call, if driving
conditions or regulations so require.
• Do not place a poable radio in the area over an air bag or in the airbag
deployment area. The radio may be propelled with great force and cause
serious inju to occupants of the vehicle when the airbag inates.

Protect your hearing
CAUTION: Exposure to loud noises from any source for
extended periods of time may temporarily or permanently
aect your hearing. The louder the radio's volume, the less
time is required before your hearing could be aected.
Hearing damage from loud noise is sometimes undetectable
at rst and can have a cumulative eect.
• Use the lowest volume necessa to do your job. Turn up the volume only if
you are in noisy surroundings.
• Limit the amount of time you use headsets or earpieces at high volume.
• When using the radio without a headset or earpiece, do not place the
radio's speaker directly against your ear.
• Use carefully with the earphone maybe possible excessive sound pressure
from earphones and headphones can cause hearing loss.
Batteries Safety information
•usable extinguishing agent: water, d power,carbon dioxide
•Since batteries are sensitive to high temperatures when storing them, keep
them in a cool and d place. The recommended temperature should be
between +10 ℃and +25℃and never exceed +30℃.
Batteries should therefore not be stored next to radiators or boilers nor in
direct sunlight. Extremes of humidity (below 35% and above 95% relative
humidity for sustained periods should be avoided since they are detrimental
to both batteries and packing. Although the storage life of batteries at room
temperature is good, storage is improved at lower temperatures provided
special precautions are taken. Also, accelerated warming is harmful.
•Turn o your radio before removing or installing a batte. Store spare
batteries securely. Dispose of used batteries immediately and safely.
•The batte supply terminals are not to be sho-circuit.
•Do not dismantle, open or shred batteries. Batteries should be dismantled
only by trained people. Do not force discharge, recharge, disassemble, heat
above 55 ℃or incinerate. Doing so may result in inju due to venting, leak-
age or explosion resulting in chemical burns.
•Batteries shall be charged at 10℃~40℃ environment temperature specied.
If the environment temperature is lower than 0℃, the charge shall be prohib-
ited.
•Rechargeable batteries are only to be charged by adults.Non-rechargeable
batteries are not to be recharged.
•The plug of the adapter is considered a disconnect device. The socket-out-
let shall be installed near the equipment and shall be easily accessible.
WARINING:CHOKING HAZARD-Small Pas.
