Charging the Battery
1. Using the Battery
The battery pack is not charged at the factory, please charge it before
use. To extend the battery pack lifetime, please not in use and do not
leave the battery in hot or cold place.
2. Battery Characteristics
The battery will slowly wear out even not in use. After charging and
recharging, it's normal that the talk and standby times are noticeably
shorter than normal times. If leaving the battery in very hot place or
conditions, it will reduce the capacity and lifetime of the battery.
Overcharging may also shorten its lifetime.
3. Charging the Battery
Please charge your battery only with our approved charger. Initially
charging the battery pack after purchase or extended storage (greater
than 2 months) will not bring the battery pack to its normal operating
capacity. After repeating the charge/discharge cycle two or three
times, the operating capacity will increase to normal level.
Please charge the battery pack as follows:
●Insert the adapter and make sure the contacts are in contact with the
socket.
●Insert the Type-C plug into the Type-C charging jack on radio battery.
●The charging LED lights red and charging begins.
● After charging when the light turns to green, it means the battery
pack is fully charged. Then you can take off radio and use it
⚠ Caution
• Make sure the radio is powered off before charging and do not use the radio during
charging.
• Read the safety information booklet in advance to get necessary safety information.
