Rechargeable and Backup Batteries
The GMS-2 comes equipped with a rechargeable battery (Figure 1-2)
for powering the unit. The battery can be charged in the unit or in an
optional battery charger. A backup battery is also located in the
battery pocket and the unit’s serial number is located under the
battery.
The battery provides seven hours of operation, depending on the
mode of the receiver. Under normal conditions, the backup battery
provides eight to ten years of power backup for data and system
integrity.
