BATTERY OPTIONS
The GX660 comes with a Li-Ion (Lithium Ion) rechargeable
battery. The GX660 battery pack will provide convenient, long
life service, and will operate your radio for approximately 12
hours on a single charge. The length of service depends largely
on how much time you spend transmitting, and what transmit
power you use.
Charging
A feature of the Li-Ion pack is that you can recharge at any
time. The standard charger will completely recharge the
GX660 battery pack in approximately 12 hours. The GX660
radio can be used with the charger attached or removed. The
GX660 will not be damaged by extended charge times. When
the radio is connected to the charger and power is present,
the LED on the outside of the charger will be red. When
battery is fully charged the ‘LED’ will turn to green.
NOTE: The battery charger does not act as a primary
power source.
Battery pack assembling instructions
When you insert the battery pack, make sure you follow the
