CHECK THE TELEPHONE LINE CONNECTION
CHECK THE TELEPHONE JACK
CONNECT THE MODEM DIRECTLY TO THE TELEPHONE WALL JACK
USE A DIFFERENT TELEPHONE LINE —
• Verify that the telephone line is connected to the jack on the modem (the jack has
either a green label or a connector-shaped icon next to it).
• Ensure that you hear a click when you insert the telephone line connector into
the modem.
• 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 line.
