Battery

The system uses a nickel metal hydride (NiMH) battery as its transient power source. The
battery pack installs in the compartment at the bottom of the base unit. The battery pack
lasts approximately 2.0 hours under typical operating conditions and recharges in approxi-
mately 1.5 hours. A bridge battery is provided as an emergency backup. It backs up mem-
ory and system status for up to 5 minutes under Suspend mode.
