If you purchased the optional battery for the PR-7XX, it can be recharged via the USB interface. The USB
power type in this menu defines how the battery is charged. Choices are
High Power (default), Low Power
and None. With High Power selected, the PR-7XX expects the PC to supply 500 mA at the USB interface.
Low Power is for devices that support 100 ma or less. Most modern computers support the High Power
mode. The USB interface functions normally for communications purposes regardless of the power
state of the USB Hub Type selected.
