human injury, treat any battery with care.

Do not short out the battery terminals or dispose of the battery in fire. Never

attempt to disassemble the battery. If discarded, the battery should be thrown

into dedicated battery recycle box.

Normal operation

 Please charge the battery indoor to ensure the optimal charging effect.

 In general, the battery can be removed if the charger indicator turns from red to

green.

 Turn off the radio when charging the battery inside the radio.

 Do not charge the battery if its power hasn’t been used up (if the power used up,

the radio will give alert tone), otherwise, the battery life will be shortened.

 Do not return fully charged batteries to the charger for an “extra boost”. This

action will significantly reduce cycle life.

To prolong battery life

 Battery performance will be greatly decreased under -20℃ temperature. Please

use back-up battery in cold weather. The cold battery unable to work in this

situation may work under room temperature, so keep it for later use.

 The dust on the battery contact may affect the life cycle of the battery. Please

use clean dry cloth to wipe it before the insertion of the battery into the radio.

Battery storage notice

1. Due to the self-discharge, the battery which will not be used for a long time

should be stored after full charge to avoid the damage to the battery because of

over-discharge.

2. Take out the battery stored for about 6 months to charge it, to avoid the influence

of electrolyte over-discharge on battery capacity.

Notice the ambient humidity and temperature for the battery storage. Please

store it in cool dry area with room temperature, to decrease self-discharge.

Battery charging

When radio LED flashes red and three Beeps sound every 30 seconds after the

battery is installed, that means battery power is low. Please charge the battery.

You are recommended to use the approved, supplied charger; Charger LED will

indicate the charging status.
