Battery information

●The first use of the battery

Since the battery is not fully charged at the factory, please charge the

new battery before use. Under normal circumstances, the battery when

used for the first time, need to charge 4 hours, lithium-ion battery

charging using slow charge or fast charge can be performed when

charging. It is recommended that the new battery be operated as above

for the first three uses. When you find the battery power is low, you need

to charge the battery.

●Suitable battery type

Please use the specified battery for charging; use of other batteries may

cause explosion, resulting in human injury.

●Battery safety attention

1. Do not allow metal contacts (including coins, keys, jewelry, or other

conductive metal) to be touched by the battery contacts or pole pieces.

Otherwise, the battery may short circuit, discharge, heat or leak, which

may result in damage to the item or personal injury. Therefore, be careful

when handling any battery.

2. Do not short-circuit the battery terminals or discard the battery in a fire.

Do not disassemble the battery pack. When the battery is discarded,

please put into a dedicated battery recycling box.

●Battery normal operation instructions

>Please charge the battery indoors, battery charging at room

temperature best.

06 07

>Under normal circumstances, the charger indicator from red to green

when the battery is fully charged, at this time the battery can be

removed. >You can charge when Battery installed in the walkie-talkie, but when

charging is best to turn off the walkie talkie, to ensure that the battery is

fully charged. >Please do not charge the battery when the battery power is not used up

(after the battery is exhausted, the voice prompt alarm will be given),

which will shorten the service life of the battery. >Do not put a fully charged battery back on the charger to "power up"

again, as this operation significantly reduces the cycle life of the battery.

●Extend battery life

>Battery performance will reduce below -20 ℃ temperature conditions.

Prepare back-up batteries for use in colder weather. Please do not throw

away cold batteries that cannot work. These batteries may be used at

room temperature. >Dusting the battery contacts may affect the battery life. Please wipe the

contacts with a clean, dry cloth before inserting the batteries into the

walkie-talkie.

●Battery storage needs to know

1.Since the battery will have a self-discharge phenomenon, the battery

when not in use for a long time, please fully charge the battery and then

stored to avoid over-discharge of its battery to damage the battery.

2. When the battery is in storage, remove the battery to recharge when

stored about 6 months. To avoid over-discharge of electrolyte affect

battery capacity.

3. Pay attention to the temperature and humidity of the battery storage

environment. Store the battery at room temperature in a cool, dry place

to minimize self-discharge of the battery.

●Battery Voltage & Power Indication

If the dealer has set the 【battery power prompt】 shortcut key for the

product, you can press and hold the shortcut key to check the remaining

battery power by LED indicator, tone and battery icon. Release the

shortcut to cancel viewing the remaining battery power. The top right of
