BATTERY INFORMATION

Charging the Battery Pack

The battery pack is not charged prior to despatch. Therefore please charge it before use.

However charging the battery pack for the rst time after purchase or extended storage
may not bring the battery pack to its normal operating capacity. If this is the case fully charge and discharge

it for two or three times and the operating capacity will reach its best performance. The battery pack life

is over when its operating time decreases significantly even though it is fully and correctly charged.

Charger Information

Please use the specic charger designed for Max-850. Using other chargers could cause an explosion

and personal injury. After installing the battery pack, if the radio displays low battery with a red ashing

light or voice prompt (If programmed), please charge the battery.

NOTES

Do not short the battery terminals or ▼ throw the battery into re. Never attempt to remove the
casing from the battery pack. No responsibility will be taken for any modifications to your product.

The ambient temperature should be between 5 ▼

℃

and 40℃while charging is in progress.

Charging outside this range may not fully charge the battery.
Always switch OFF the transceiver before charging. Otherwise, if it is not switched off it will interfere with ▼

To avoid interfering with the charging, please do not cut off the power or remove the battery during

▼

charging.

the charging process.

BATTERY INFORMATION

Do not recharge the battery pack if it is already fully charged. This may shorten the life of the ▼
battery pack or damage the battery pack.
Do not charge the battery or transceiver if it is damp. Dry before charging to avoid danger. ▼

WARNING:

When keys or other conducting items come into contact with the battery terminal, the battery may cause

damage or be dangerous. If the battery terminal does short circuit it will generate excessive heat,
please be careful when you carry or are using the battery, put the battery or the radio into an
insulated container. Do not put it into metal container.

How to Charge

Plug the AC adaptor into the power outlet, and then 1.
plug the cable of the AC adaptor into the DC jack
located on the back of the charger. The backlight
lights orange (1s) and then goes out. Wait before
charging.
Plug the battery or transceiver into the charger. 2.
Make sure that the battery terminals are firmly in contact
with the charging terminals. The backlight will

ash red. Pre-charging begins.

Aft er p re- cha rgi ng f or a bo ut 5 m in ute s, the 3.

backlight will stop ashing. Charging begins.
It takes approximately 4 hours to fully charge the battery. When the lamp goes to green, the charging 4.
is nished. Remove the battery or the transceiver equipped with the battery from the charger.

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.

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.
