Getting started
Charging the Battery
Plug the power adapter into the proper AC wall outlet and insert the DC plug in the charger
base. The Red LED will flash for 4.5 seconds after it is first turned on.
Insert the battery or the radio to be charged into the charger slot. Please turn off the radio
before inserting it into the charger.
Make sure the battery is in good contact with the charger terminals. When the red indicator is lit,
the charger begins to charge the battery.
After charging for about 3 hours, the red LED will turn OFF and the green LED will turn on
indicating the battery has been fully charged.
Only for NiMH battery on the first charge, please leave the battery in for two more hours after
the green light first turns on before you remove it from the charger to achieve the best
performance of the battery. Then you can disconnect the power adapter from the AC outlet.
If the Red LED flashes quickly (0.2s on 0.2s off), this means the charging process has stopped
because the charging temperature is too high or the battery has a problem. If that happens the
charger enters a protective state and no more charge is delivered to the battery. Please stop
charging in such situation and remove the battery from the charger.
Notice:
The new battery is not fully charged in the factory, and needs to be fully charged when you use
the radio for the first time.
The radio is supplied with a standard battery manufactured by the factory.

The battery, after been in storage for a long period ,will not reach the full capacity till several
charging and discharging (during use) cycles.
Do not recharge the battery after it has been fully charged or it is partially discharged, otherwise
it might affect the battery life or performance. Remove the battery from the charger after
charging is finished.
If the radio enters a low battery warning state, please recharge the battery. Do not use the radio
in a low power warning state because it will affect the battery life and performance.
Installing/Removing the Battery Pack
To install the battery, please place it into the groove on the top of the radio chassis about 5mm
away from latch.
If the radio has the belt clip installed, you will have to press one side of the clip to raise it and
then slide the battery in proper position.
Press the battery with your fingers and push the battery until you hear a latch click. The battery
is now installed.
Removing the battery pack
If you want to remove the battery from the radio, first press the battery latch located on the
bottom of the radio, and then press down to slide the battery about 5mm to release the
latch.
Notice:

Installing the Antenna
Screw the antenna into the connector at the top of the radio by holding the bottom of the
antenna and turn it clockwise until secure.
Install external speaker/MIC
Open the cover of the jack for external speaker/MIC, and then insert the plug of the external
speaker or microphone into the jack on the radio. When inserting the accessory plug, make sure
it is properly aligned (straight) to avoid internal damage to the connector in the radio.

Installing/Removing the Belt Clip
Use the 2 screws (M2.5x8.0) supplied with the radio and insert these screws through the holes
in the radio clip and into the holes in the aluminum case. If you want to remove the clip from
