About Your Computer
A C ADAPTER CONNECTOR — Attaches an AC adapter to the computer. The AC
adapter converts AC power to the DC power required by the computer. You can
connect the AC adapter with your computer turned on or off.
CAUTION:
The AC adapter works with electrical outlets worldwide. However,
power connectors and power strips vary among countries. Using an incompatible
cable or improperly connecting the cable to the power strip or electrical outlet
may cause fire or equipment damage.
NOTICE:
When you disconnect the AC adapter cable from the computer, grasp the
connector, not the cable itself, and pull firmly, but gently to help prevent damage to
the cable.
MODEM CONNECTOR ( R J - 1 1 )
Connect the telephone line to the modem connector.
For information on using the modem, see the online
modem documentation supplied with your computer.
