Battery Information (Take a keypad type model for example)
Initial use of the battery
The battery is not fully charged at the factory. Please charge the new battery before
initial use. In general, the battery should be charged for 12 hours before initial use,
which is suitable for Ni-Cd, Ni-MH or Li-ion battery charged with slow or rapid charger. It
is recommended to take this step during the first three times of use. When the battery
power is low, it needs to be charged.
Applicable Battery Packs
Charge only the HYT approved battery packs. Other batteries may burst and cause
personal injury.

Safety attention
1. Conductive metals including jewelry, key, etc, may result in short circuit, discharge,
generation of a large quantity of heat, or leakage when coming into contact with
battery contacts or electrodes. To avoid damage to articles or human injury, treat any
battery with care.
2. 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.
3. 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.
