Connecting the AC adapter
Do not attempt to disassemble the AC
adapter. The AC adapter has no user-replaceable or serviceable parts
inside. Dangerous voltage in the AC adapter can cause serious
personal injury or death. The AC adapter is intended for use with a
computer and must meet EN609050 standards.
Do not cover or place objects on the AC
adapter. Keeping the adapter clear of objects lets the adapter cool
properly during use.
Only use the AC adapter that comes with your NEC Versa LitePad
tablet PC. Although other adapters look similar, using them can
damage your system.
Note
For information about charging and using the battery pack,
see "Battery Operation" in this chapter.
