2. BATTERY INFORMATION
2.1 Charging the Battery Pack
The Li-ion battery pack is not charged at the factory; please charge it before use. Charging the battery pack for the first time
after purchase or extended storage (more than 2 months) may not bring the battery pack to its normal maximum operating
capacity. Best operation will require fully charging/ discharging the battery two or three times before the operating capacity
will reach its best performance. The battery pack life may be depleted when it’s operating time decreases even though it has
been fully and correctly charged. If this is the case, replace the battery pack.
2.2 Charger Supplied
Please use the specified charger provided by our company. Other models may cause explosion and personal injury. After
installing the battery pack, and if the radio displays low battery with a voice prompt, please charge the battery.
2.3 Use Caution with the Li-ion Battery
a. Do not short the battery terminals or throw the battery into a fire. Never attempt to remove the casing from the battery pack,
as our company cannot be held responsible for any accident caused by modifying the battery.
b. The ambient temperature should be between 5℃-40℃ (40˚F - 105˚F) while charging the battery. Charging outside this
range may not fully charge the battery.
c. Please turn off the radio before inserting it into the charger. It may otherwise interfere with correct charging.
d. To avoid interfering with the charging cycle, please do not cut off the power or remove the battery during charging until the

When keys, ornamental chain or other electric metals contact the battery terminal, the battery may become damage or
injure a human. If the battery terminals are short circuited it will generate a lot of heat. Take care when carrying and
using the battery. Remember to put the battery or radio into an insulated container. Do not put it into a metal
container.
2.4 How to Charge
a. Plug the AC adaptor into the AC outlet, and then plug the cable of the AC adaptor into the DC jack located on the back of
the charger. The indicator light blinks orange and is then ready to charge a battery.
b. Plug the battery or the radio into the charger. Make sure the battery terminals are good in contact with charging terminals.
The indicator light turns to red--- charging begins.
c. It takes approximately 2-5 hours to fully charge the battery. When the lamp lights green, the charging is completed. Remove
the battery or the radio unit with its battery from socket.
When charging a radio (with battery) the indicating lamp will not turn into green to show the fully charged status if
the radio is powered on. Only when the radio is switched off will the lamp indicate normal operation. The radio
consumes energy when it is power-on, and the charger cannot detect the correct battery voltage when the battery has
been fully charged. So the charger will charge the battery in constant voltage mode and fail to indicate correctly when
the battery has been fully charged.
2.5 LED Indicator STATUS LED

5. BASIC OPERATIONS
5.1 Power on the radio
•Turning the unit on
To turn the unit on, simply rotate the volume/power knob clockwise until you hear a "click". If your radio powers on
correctly there should be an audible double beep after about one second and the display will show a message or flash the LCD
depending on settings for about one second. Then it will display a frequency or channel. If the Voice prompt is enabled, the
voice will announce "frequency mode" or "channel mode".
•Turning the unit off
Turn the volume/power knob counter-clock wise all the way until you hear a "click". The unit is now off.
5.2 Adjusting the volume
To turn up the volume, turn the volume/power knob clock-wise. To turn the volume down, turn the volume/power knob
counter-clock-wise. Be careful not to turn it too far, as you may inadvertently turn your radio off.
5.3 Channel selection
There are two modes of operation: Frequency (VFO) mode, and Channel or Memory (MR) mode.
For everyday use, Channel (MR) mode is going to be a whole lot more practical than Frequency (VFO) mode. However,
Frequency (VFO) mode is very handy for experimentation out in the field. Frequency (VFO) mode is also used for
programming channels into memory.
In Channel (MR) mode you can navigate up and down the channel by using the / keys or the encoder.
Ultimately which mode you end up using will depend entirely on your use case.
