CAUTIONS
transceiver is excellent designed with advanced technology. The following tips will be helpful for you in
performing your obligation under warranty and understanding the safety of transceiver usage.
1.Keep the transceiver and accessories away from children.
2.Please do not try to open or modify the transceiver without permission, non-professionals operation may also cause
damage.
3.Please use assorted battery and charger to avoid damage.
4.Please use assorted antenna to ensure the communication distance.
5.Please avoid exposing the radio under the sunshine for a long time or storing it in too hot places. High temperature will
shorten the life of electronic devices.
6.Please avoid storing the radio in the dusty, dirty and damp areas.
7.Please keep the radio dry. Do not wash radio with ardent chemicals and detergents.
8.Do not transmit without antenna.
9.When using this transceiver, we recommend transmitting for 1 minute then receiving for 4 minutes. continuously
transmitting for long time or working in high power will heat the back of the transceiver. Do not place the transceiver's hot
back close to any plastics.
10.If any abnormal smell or smoke coming from the transceiver, please turn off the power instantly and take off the battery
and its case. Then contact local dealers.
NOTE：
All the above tips apply for your transceivers' accessories. If any device can not operate
normally, please contact with local dealers.
If you use any accessories made by other companies, company does not guarantee the

BATTERY INFORMATION
Charging Operation
The battery is not charged at the factory, please charge it before use. Charge the battery for the rst time
after purchase or extended storage (more than 2 months) may not bring the battery to its normal operating
capacity. After repeating fully charge/discharge cycle for two or three times, the operating capacity will
reach the best performance. The battery life is over when its operating time decreases even though it is
fully and correctly charged. Replace the battery.
Battery Charger Type
Please use our company's designated charger, other models may cause explosion and injure people. After
installing the battery, if the radio red light twinkles and remind changing battery, please charge the battery.
Notice for Charging Battery
Do not shortcircuit our company designated charger. Never attempt to remove the casing from the ▲
battery, we show no responsibility on the faulty caused by modifying freely without permission of our
factory.
The ambient temperature should be between 5 ▲℃ and 40℃ in charging. Charging outside this range
may not fully charge the battery.
Always switch off the transceiver equipped with a battery before charging. Otherwise, it will interfere ▲
with correct charging.
To avoid interfering the charging procedure, please do not cut off the power or take out the battery ▲
during charging.
04
How to Charge
1.Plug the AC adaptor into the AC outlet, then plug the cable of
AC adaptor into the DC jack, the indicator lights orange for 1s
and turns into GREEN---waits to charge.
2.Slide the battery or transceiver with battery into the charger;
make sure the battery terminals are in contact with the
charging terminals well. LED turns into twinkling RED---pre-
charging begins.
3.Pre-charging for about 5 minutes, LED twinkles stop then
charging begins.
4.It takes about 4 hours to fully charge the battery, when LED
turns into GREEN — full charged.
BATTERY INFORMATION
WARNING:
When keys or ornamental chains and other electric metals contact with the battery terminals, the battery
may cause damage or hurt bodies. If the battery terminal short circuit, it will generate a lot of heat, please
be careful when you bring or use the battery, please put battery or radio into insulated container. Do not put
it into metal container.
Do not recharge the battery if it is already fully charged. This may shorten the life of the battery or ▲
damage the battery.
Do not charge the battery or transceiver if it is damp. Dry it before charging to avoid danger. ▲
05
NOTE: When charging a power-on transceiver equipped with battery, the LED will not turn into green to
show the full charge status. Only when turn off the transceiver, the LED can indicate normally.
Because when the transceiver is power on, it would consumes energy, the charger cannot detect when battery
has been fully charged, the charger will charge battery in voltage consumption and fail to indicate correctly.

06
How to Store the Battery
1.If the battery needs to be stored for a long
period, the battery should be removed
from the radio. It's state of charge should
be 50-100% charged.
2.It should be kept in low temperature, dry
environment.
3.To keep away from hot places and direct
sunlight.
Charging Prompt
1.Self-examination: When charging, ORANGE light twinkles for 1 second and goes out. That means the
charger has passed its self-examination and it can charge the battery normally. If the light remains
orange or the red light twinkles, which means the charger can not pass its self-examination or charge
the battery.
2.Trickle pre-charging: When the battery has been inserted into the charger and red light twinkles, which
means the remnant voltage is low, the charger trickle charge the battery (pre-charging status), until the
battery reaches a certain electric quantity, the charger automatically turns into normal charging. And
if the red light stop twinkling, which means the remnant voltage meets a certain electric quantity, the
charger will charge the battery normally.
BATTERY INFORMATION
NOTE:The time for Trickle pre-charging is not exceed 30m. After 30m, the red indicator is still twinkling,
it means it is unable to charge battery. Please kindly check battery and charger.
WARNING
▲Do not short circuit battery terminals.
▲Never attempt to remove the casing from the battery
pack.
▲Never assemble the battery in dangerous surroundings,
spark may cause explosion.
▲Do not put the battery in hot environment or throw it
into fire, it may also cause explosion.

The SAR limit of USA (FCC) is 8 W/kg averaged over one gram of tissue. Device
types 518UVII (FCC ID: T4K3208UV) has also been tested against this SAR limit.
The highest SAR value reported under this standard during product certification for
use when properly worn on the body is 2.366 W/kg and for head is 3.990 W/kg.
. This device was tested for typical body‐worn operations with the back of the
handset kept 25mm from the body. To maintain compliance with FCC RF exposure
requirements, use accessories that maintain a 25mm separation distance between
the user's body and the back of the handset. The use of belt clips, holsters and
similar accessories should not contain metallic components in its assembly. The use
of accessories that do not satisfy these requirements may not comply with FCC RF
exposure requirements, and should be avoided.
The device was SAR tested a distance of 25mm for the held to face position.
This device must be restricted to work related operations in an Occupational/Controlled RF
exposure Environment, not exceeding a maximum transmitting duty factor of 50%. All qualified
end‐users of this device must have the knowledge to control their exposure conditions and/or
duration to comply with the Occupational/Controlled MPE limit and requirements.
