Power Management
Battery-powered units can utilize a rechargeable Nickel Metal Hydride (NiMH)
battery pack that has an average operating time of six hours on a full charge with
power management.
As with all battery-powered devices, the operating time is completely dependent
on the environment, device usage, and the number and type of power-drawing
peripherals attached. The battery discharge rate in a full “Power Off ” state is only
slightly higher to the self-discharge rate of the battery itself.
