Battery
Safety Precautions
The battery option is shipped uncharged from the factory. Please charge a new battery or
battery that has not been used for a long time prior to use. The maximum capacity of the
battery is achieved only after 2 or 3 charging and discharging cycles. When the battery
power runs low, please recharge the battery or replace with a refresh one.
Initial Use
The HYT approved battery is shipped not fully charged at the factory. Prior to using a new
battery, please charge it for 12 hours, which applies for Ni-Cd, Ni-MH and Li-Ion battery
charged with slow or rapid rate charger. It is recommended to take this step for the first
three times of use. When the battery power runs low, please recharge the battery.
Applicable Battery Packs
To reduce the risk of injury, charge only the battery specified by the manufacturer. Other
batteries may burst, causing bodily injury and damage.
Caution:
1. Do not short circuit the battery terminals or discard the battery in fire. Never attempt
to disassemble the battery.
2. The battery should be charged at 5℃ ~ 40℃, temperature out of this range could
result the battery not fully charged.
3. When charging a battery attached to a radio, turn the radio off to ensure a full charge.
4. Do not cut off the power supply or remove the battery when charging a battery.
5. If the operation time will not increase even though the battery is properly charged, this
means the battery life cycle is over, please replace with a new one.
6. Do not return fully charged batteries to the charger for an “extra boost”. This action
will significantly reduce battery life.
7. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.
All batteries can cause property damage and/or bodily injury such as burns if a conductive
material such as jewelry, keys, or beaded chains touch exposed terminals. The
conductive material may complete an electrical circuit (short circuit) and become quite hot.

may work under room temperature, so keep it for later use.
The dust on the battery contact may affect battery life. Please use clean dry cloth to
wipe it before the attaching the battery to the radio.
Battery Storage
1. Considering the battery's self-discharge characteristics, fully charge the battery prior
to long time storage, to avoid battery damage due to over-discharge.
2. Recharge the battery after 6 months’ storage, to avoid reducing battery capacity due
to over-discharge.
3. Notice the ambient humidity and temperature for the battery storage. Please store it in
cool dry area under room temperature, to reduce self-discharge capacity.
Charging the Battery
When the LED flashes red and three beeps sound every 30 seconds indicating the battery
power runs low, please recharge the battery.
Only the charger specified by the manufacturer may be used. The charger’s LED
indicates the charging progress.

Please follow these steps:
1. Plug the power cable into the adapter.
2. Plug the DC connector of the adapter into the DC socket on the back of the charger.
3. Place the radio with the battery attached, or the battery alone, in the charger.
4. Plug the AC connector of the adapter into the AC outlet socket.
5. Make sure the battery is in well contact with the charging terminals, the charging
process initiates when the red LED lights.
6. The greed LED lights about 3 hours later indicating the battery is fully charged. Then
remove the radio with the battery attached or the battery alone from the charger.
Note:
a) It is normal that the LED flashes before placing the battery into the charger.
b) Do not place another battery into the charger until the charger LED is stabilized.
c) After the battery is placed properly, the LED solidly glows red indicating the
battery is charging, or flashes indicating the battery is damaged or the ambient
temperature is over high/low.
When troubleshooting, always observe the color of the LED:
No LED Indication?

1. Remove the battery from the charger, and:
a) make sure that it is a HYT authorized battery. Other batteries may not charge.
b) Remove power from the battery charger and, using a clean dry cloth, clean the
gold metal, charging contacts of the battery and charger.
2. The battery temperature may be above 45℃.
3. Defective battery, please replace it with a new one.
4. Power up the charger and place the battery back into the charger pocket. If the LED
indicator continues to flash red, replace the battery.
Note:
Rapid charging outside of the stated temperature limits (5℃~40℃) can drastically
reduce the life expectancy of the battery.
When the battery charger detects the proper battery conditions, rapid charging begins
automatically (steady red LED).
If the battery temperature is above 45℃, the charger will report the fault by flashing
red LED rapidly (0.2s on/0.2s off), and will not charge until the battery temperature is
below 45℃, with red LED solidly glows (Ni-MH battery only).
Antenna
Stubby antennas are ideal for communication within limited range. Fine and long
antennas optimizes communication coverage, ideal when the radio is worn on
the belt because they are flexible and soft.
Rainy days or forest locations may narrow your communication range, please
prepare in advance to avoid potential inconvenience.
