• 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, bypass them and use the telephone to
connect the modem directly to the telephone wall jack. If you are using a line that is
3 meters (10 feet) or more in length, try a shorter one.
