BATTERY INFORMATION
NOTE: when charging a powered up transceiver equipped with a battery, the indicating lamp will not
turn to green to show the fully charged status. Only when the transceiver is switched off, can the
lamp indicate normally. The transceiver consumes energy when the power is on, and the charger can
not detect the voltage when the battery has been fully charged. So the charger will charge the battery in
constant voltage and fail to indicate correctly whether the battery has been charged fully.
Charging Process5.
Charging Status backlight Status
Standby (Self-test lights orange 1second when power on) None
Pre-charging (Pre-charging stage) Red light flashes for about 5 minutes

BATTERY INFORMATION
Normal Charging Tips
Self- Test:1. When charging, orange light ashes for 1 second and goes out , which means
the charger has passed its self-test and it can charge the battery normally. If the light
remains orange or the red light ashes, it means the charger has not passed its self-test or
charged the battery.
Trickle Pre-Charging:2. If the red light ashes when the battery is inserted into the charger, it means
the remaining voltage is low and the charger is trickle-charging the battery (Pre-Charging Status). The
charger will automatically start normal charging when the battery reaches a certain electric
quantity. However if the red light stops ashing, it means the voltage meets a certain electric
quantity and the charger will charge the battery normally.
How to Store the Battery
If the battery needs to be stored, keep it in status of 50% discharged.1.
It should be kept in low temperature and dry environment.2.
Keep it away from hot places and direct sunlight.3.
If the trickle-charging lamp continues flashing after 30 minutes, check that the
battery's terminals are in contact with the charger.
This may indicate faults in the charger or battery.
