◇ Do not charge your battery in a potentially explosive atmosphere.
◇ To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted
notices instruct you to do so.
◇ When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in accordance
with airline regulations or crew instructions.
◇ To avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting caps,
in a blasting area, or in areas posted: “Turn off two-way radio.” Obey all signs and instructions.
◇ For vehicles with an air bag, do not place a radio in the area over an air bag or in the air bag deployment area.
◇ Do not expose the radio to direct sunlight over a long time, nor place it close to heating source.
◇ When transmitting with a portable radio, hold the radio in a vertical position with the microphone 3 to 4 centimeters
away from your lips. Keep antenna at least 2.5 centimeters away from your body when transmitting.

Battery Information
Initial Use
New batteries are shipped uncharged from the factory. Charge a new battery for 5 hours before initial use, and this is true to
Ni-Cd, Ni-MH and Li-Ion batteries charged with slow or rapid rate charger. The maximum battery capacity and performance
is achieved after two or three full charge/discharge cycles. If you notice the battery power runs low, please recharge the
battery. New batteries or batteries stored for a long time may take more time to charge.
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. 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 attempt to disassemble the battery.
Battery Tips
1. When charging your battery, keep it at a temperature among 5℃ ~ 40℃ to ensure a full charge. Temperature out of the
limit will significantly reduce battery life.
2. When charging a battery attached to a radio, turn the radio off to ensure a full charge.
3. Do not cut off the power supply or remove the battery when charging a battery.
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 time (talk-time and standby time) is noticeably shorter than
normal, it is time to buy a new battery.
To Prolong Battery Life
1. Battery performance will be greatly decreased at a temperature below 0℃. A spare battery is necessary in cold weather.
The cold battery unable to work in this situation may work under room temperature, so keep it for later use.
2. The dust on the battery contact may 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 time, to avoid battery damage due to over-discharge.
2. Recharge a battery after 3 months’ storage, to avoid reducing battery capacity due to over-discharge.
3. When storing your battery, keep it in a cool, dry place under room temperature.

Charging the Battery
When the battery level is very low, please recharge the battery.
Use only the charger specified by the manufacturer. The charger’s LED indicates the charging progress.

For MCU rapid-rate
charger
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 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.
10
Troubleshooting (MCU intelligent rapid-rate charger only):
When troubleshooting, always observe the color of the LED:
No LED Indication?
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. 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 clean the gold metal, charging contacts of the battery and charger,
using a clean dry cloth.
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:
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 Information
1. Stubby antenna is ideal for communication within limited range. Thin and long antenna optimizes communication
coverage, and its flexible and soft characteristic makes it ideal for wearing your radio on the belt.
2. Communication range may vary with terrain and your operating conditions. Rainy days or forest locations may narrow
your communication range, please make preparation in advance to avoid potential inconvenience.
