Preparation
Charging the Battery
The radio is not charged before leaving the factory. Before initial use, please charge the new
battery. Initially charging the battery pack after purchase or extended storage (greater than two
months) will not bring the battery pack to its normal operation capacity, after repeating the
charge/recharge cycle two or three times, the operation capacity will increase to normal. If the
operating time of the battery does not increase after the charging, please change a new battery,
because its life is over.
Type of Charger
Please charge the battery with the charger provided by Kirisun: Charging with unauthorized
charger may cause explosion and personal injury. If the screen displays after the battery is
installed, it indicates that the battery is out of power, please charge the battery.
Attentions
Do not reverse the battery polarity or discard the battery in the fire. Never disassemble the
battery or the cover of the charger. Kirisun does not take the responsibility of any problems
which are caused by any unauthorized modification.
The ambient temperature of charging should be kept within 5~40℃. Charging beyond this
temperature range will affect the performance of the charging and the battery cannot be charged
fully.
If you are inserting the radio in the charger to charge, please turn off the radio first, otherwise
it will affect the charging.
During the charging, do not plug off or in the power supply and the battery, otherwise it will
affect the charging program.
If the battery finishes charging, do not reinsert the battery to recharge it, otherwise it will
shorten the battery life and damage the battery.
If the battery or the radio is wet, do not charge the battery immediately. Please wipe off the
liquid first so as to avoid danger.
Warning!
Contacting the conducted metal such as ornament, keys or jewelries with the battery terminal
may cause damage, personal injury. Reversing the terminals will cause large quantity of heat.
When carrying or using the battery, please put it in the insulated container, and never put it in
the metal container.
Steps of Charging
Insert the adapter to the socket of AC output, and then connect the adapter with the charger.
LED indicator lights in orange for one second and then lights off, the charger enters into standby
state.
Insert the battery or the radio into the charger base. Make sure the battery and the charger
terminal is well connected. Then LED indicator flashes in red, and the charger enters into
pre-charge state.
After about 5 minutes, LED indicator stops to flash, and the charging begins.
The battery should be charged for 4 hours. When LED indicator turns to be green, the
charging finishes. And take off the battery or the radio.
Note:
If the radio is inserted into the charger in the power-on state, the LED indicator cannot turn to
be green when the charging is complete. Only when you power off the radio, the indicator will
return to normal. (This is because the radio will consume the battery in the power-on state so
that the battery cannot be charged fully.)

Note: Error includes heat emitting from the radio, short circuit of battery or charger base.
Charging Notice
Self test: When the charger base electrifies, orange LED indicator lights for one second. If the
radio enters pre-charging state, self test passes; if the orange or red LED indicator flashes
constantly, self test fails, and charging cannot be done.
Pre-charge: Insert the battery in; red LED indicator flashes, the battery is in low voltage.
Pre-charge the battery; after the battery voltage arrives to a certain amount (red LED indicator
stops to flash), charge the battery automatically.
Note: T ime for pre-charging cannot exceed 30 minutes. If red LED indicator still flashes after 30
minutes, charging cannot be done. Please check the battery and the charger base.
Battery Storage
Keep the battery in 50% capacity in storage.
Keep the battery in cold and dry environment.
Keep the battery away from the heat source and direct sunlight.
Warning
Do not reverse the battery polarity.
Do not attempt to reassemble the battery cover.
Do not install the battery in the dangerous environment. The sparkle may cause explosion.
Do not discard the battery in the high temperature environment or fire, which may cause
explosion.
