Chapter 4
Managing Power
DCU 220 operates either on external AC power or on internal battery power.
This chapter tells you how you can effectively manage power. To maintain optimal battery
performance, it is important that you use the battery in the proper way.
AC Adapter
CAUTION:
The AC adapter is designed for use with DCU 220 only. Connecting the AC adapter to
another device can damage the adapter.
The AC power cord supplied with DCU 220 is for use in the country where you
purchased DCU 220. If you plan to go overseas with DCU 220, consult your dealer for
the appropriate power cord.
When you disconnect the AC adapter, disconnect from the electrical outlet first and
then from DCU 220. A reverse procedure may damage the AC adapter or DCU 220.
When unplugging the connector, always hold the plug head. Never pull on the cord.
The AC adapter serves as a converter from AC (Alternating Current) to DC (Direct Current)
power because your computer runs on DC power, but an electrical outlet usually provides
AC power. It also charges the battery pack when connected to AC power.
The adapter operates on any voltage in the range of 100~240 V AC.
