Connecting The Ac Adapter; Power Sources; Ac Adapter - NEC VERSA 4000 Service Manual

POWER SOURCES

For optimum performance and power conservation, use the AC adapter to power the NEC
Versa 4000 series system. Other power sources include the battery pack, the optional car
DC adapter and the optional docking station .

AC Adapter

The AC adapter allows the system to operate with AC power, recharges the battery pack,
and maintains the bridge battery. The internal backup battery allows the system to retain
system parameter information.
If the AC adapter is used primarily, remove the battery pack to reduce system weight.
Connect the AC adapter as follows:
1. Connect the adapter's DC cable to the power connector on the rear of the system.
Connect the other end to the AC adapter.
NOTE: Make sure that the AC adapter is con-
nected at all times. It will continue to charge the
battery pack and bridge battery during operation
or when the system is turned off.
CAUTION: Only use the AC adapter model
provided with the NEC Versa 4000 series sys-
tem.
