Backup Power
The device is equipped with a super-capacitor (supercap) to provide backup power to the device when the
main battery is removed. The supercap will retain random access memory (RAM) data in memory for
approximately five minutes after the main battery is removed during Hot Swap.
IMPORTANT: The supercap is automatically charged from the main battery and requires approximately
ten minutes to fully charge.
Removing and Replacing Keypads
1. Power off the device.
2. Remove the battery.
3. Using a Torx T8 screwdriver with a large grip, remove the two keypad latch screws from inside the battery
slot.
