Battery Information
Please use and charge only a TERA approved battery. Attempting to use a different
battery type may result in overheating or explosion of the battery, causing damage to
the radio and the potential for physical injury.
Notes:
1. Do not short-circuit the battery terminals or dispose the battery in fire. Never attempt to
disassemble the battery pack.
2. Charge the battery in 32-105 °F temperature. Otherwise the battery may not fully charge.
3. Turn off the radio before your initial charge. Use of the radio while charging may cause noise
or interfere during reception or transmission.
4. Do not pull/plug the adapter and the battery during charging, to avoid interference with the
charging procedure.
5. NEVER charge the battery or radio with battery if they are wet. Before charging, you should dry
them off with a towel or cloth to avoid danger.

Warning:
Conductive metals such as jewelry, keys or decorating lace may result in short circuit
and generate a large quantity of heat when coming in contact with battery electrodes.
Treat any battery carefully especially when placing it into pocket, wallet or other metal
container as it can short out.
Charge Operation
Please charge as follows:
1. Turn off the radio.
2. Plug the AC connector of adapter into an AC output socket

TERA
3. Vertically insert the battery or radio equipped with battery into the charger. Make sure the
charger and battery are well contacted.
4. After the radio and/or battery are inserted into the charger, the LED glows red and that means
the charger is ready for normal charging; if the LED flashes red, it means the remaining battery
power is too low and a trickle charge is in process. After the battery power has reached a
certain amount during trickle charge, the charger automatically turns to normal (fast) charge
mode (solid red colored LED).
5. The battery is fully charged (97%-100%) when LED glows green. The charger stops charging
automatically.
Caution when Charging the Battery
1. The battery is not fully charged from the factory. Please charge the battery before initial use or
after long-period of storage.
2. Repeat charging 2 to 3 times will make the battery reach its best capacity. Please replace or
charge the battery if battery power is low after repeated charges.
Note
Trickle charge is not allowed to exceed 30 minutes. If the LED is still flashing in red after 30
minutes, it means that the charger cannot provide power to the battery. Check if the battery or
charger is damaged.
