Setup and Operation 2-23
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.
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.
If the AC adapter is used primarily, remove the battery pack to reduce system weight.
CAUTION:
Only use the AC adapter model
provided with the NEC Versa 4000 series sys-
tem.
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.
