Modem and Network Connections
Å
WARNING: To reduce the risk of electric shock, fire, or damage to the
equipment, do not plug a telephone cable into the RJ-45 network jack.
Å
WARNING: Connecting the notebook to a digital line can
permanently damage the modem. Immediately disconnect your modem
cable if it is accidentally connected to a digital line.
Ä
CAUTION: Your built-in modem might not work with multiple phone
lines or a private branch exchange (PBX), cannot be connected to a
coin-operated telephone, and does not work with party lines. Some of
these connections might result in excess electrical voltage and could
cause a malfunction in the internal modem. Check your telephone line
type prior to connecting your phone line.
Ä
CAUTION: Jacks for digital PBX systems might resemble RJ-11
telephone jacks, but they are not compatible with the modem.
A modem must be connected to an analog telephone line.
The maximum speed for faxing is 14.4 Kbps, even though the
modem is capable of downloading at higher speeds.
For more information on connecting and configuring your
modem, refer to the
Modem and Networking guide on this CD.
