Battery Information
Initial Use
New batteries are shipped uncharged fro the factory. Charge a new battery for 5 hours

full charge/discharge cycles. If you notice the battery power runs low, please recharge the

9
battery.
Applicable Battery Packs
To reduce the risk of injury, charge only the battery specified by the anufacturer. Other
batteries ay burst, causing bodily injury and da age.
Caution:
1. To avoid risk of personal injury, do not dispose of batteries in a fire!
2. Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as
household waste.
3. Never atte pt to disasse ble the battery.
Battery Tips
1. When charging your battery, keep it at a te perature a ong 5℃-40℃. Te perature
out of the li it ay cause battery leakage or da age.
2. When charging a battery attached to a radio, turn the radio off to ensure a full charge.
3. Do not return a battery to the charger before the battery power runs low. This action
will significantly reduce battery life. Never take the charger as a stand for your radio.
4. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.
5. The battery will eventually wear out. When the operating ti e (talk-ti e and standby
ti e) is noticeably shorter than nor al, it is ti e to buy a new battery.
To Prolong Battery Life
1. Battery perfor ance will be greatly decreased at a te perature below 0℃. A spare
battery is necessary in cold weather. The cold battery unable to work in this situation
ay work under roo te perature, so keep it for later use.
2. The dust on the battery contact ay cause the battery cannot work or charge. Please
use clean dry cloth to wipe it before attaching the battery to the radio.
Battery Storage
1. Fully charge a battery before you store it for a long ti e, to avoid battery da age due
to over-discharge.
2. Recharge a battery after several onths’ storage (Ni-MH & Ni-Cd batteries: 3 onths;
Li-Ion & Li-poly er batteries: 5 onths), to avoid reducing battery capacity due to

10
over-discharge.
3. When storing your battery, keep it in a cool, dry place under roo te perature.
Charging the Battery
Use only the charger specified by the anufacturer. The charger’s LED indicates the
charging progress.
Status Charger LED
Standby (no-load) Red LED flashes slowly (0.2s
on/3s off )
Battery is charging Red LED solidly glows
Battery is fully charged Green LED solidly glows
Error Red LED flashes rapidly (0.2s
on/0.2s off)
Please follow these steps:
1. Plug the power cord into the adapter.
2. Plug the AC connector of the adapter into the AC outlet socket.
3. Plug the DC connector of the adapter into the DC socket on the back of the charger.
4. Place the radio with the battery attached, or the battery alone, in the charger.
5. Make sure the battery is in well contact with the charging ter inals. The charging

11
process initiates when the red LED lights.
6. The greed LED lights about 3 hours later indicating the battery is fully charged. Then
re ove the radio with the battery attached or the battery alone fro the charger.
Troubleshooting MCU intelligent rapid-rate charger only):
When troubleshooting, always observe the color of the LED:

1. Make sure that the power cord is plugged into an appropriate AC outlet.
Red LED flashes rapidly 0.2s on/0.2s off)?
1. Re ove the battery fro the charger, and:
a) Make sure that it is a HYT authorized battery. Other batteries ay not charge.
b) Re ove power fro the battery charger, and clean the gold etal, charging
contacts of the battery and charger, using a clean dry cloth.
2. The battery te perature ay 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:
When the battery charger detects the proper battery conditions, rapid charging begins
auto atically (steady red LED).
If the battery te perature 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 te perature is
below 45℃, with red LED solidly glows (Ni-MH battery only).
Antenna Information
1. Stubby antenna is ideal for co unication within li ited range. Thin and long antenna
opti izes co unication coverage, and its flexible and soft characteristic akes it
ideal for wearing your radio on the belt.
2. Co unication range ay vary with terrain and your operating conditions. Rainy
days or forest locations ay narrow your co unication range, please ake
