•
Disconnect the telephone line from the modem and connect it to a
telephone, then listen for a dial tone.
•
If you have other telephone devices sharing the line, such as an answering
machine, fax machine, surge protector, or line splitter, then bypass them
and connect the modem directly to the telephone wall jack. If you are
using a line that is 3 m (10 ft) or more in length, try a shorter one.
