Troubleshooting
If the Modem Dials, But You Cannot Hear It
■ If your model has an audio mute light, make sure it is turned
off. If it is on, press the audio mute button.
■ Check the speaker volume setting.
■ In Control Panel, open Phone and Modem Options, then
select the modem and select Properties. Check the volume
setting on the General tab.
If the Modem Connects, But Transferred Data Is Bad
■ In Control Panel, open Phone and Modem Options. Make
sure the parity, speed, word length, and stop bits match on
the
sending and receiving modems.
■ Try a different phone line or dial a different server number.
If the Modem Causes an ERROR Message
A string of AT commands may contain an incorrect command. If
you entered commands as extra settings for the modem in Control
Panel or in your communications software, check the commands.
If the Modem Does Not Fax
■ If you are using fax Class 2 in the fax software, try using
Class
1.
■ Close any other communications programs.
■ If you are faxing by printing from an application, make sure
you have selected the fax printer.
■ Try turning off power management features temporarily.
If Excessive Line Current Is Detected
Make sure you are using an analog telephone line (2, 3, or
4
wires). You must not use a digital line. In a hotel, ask for a
data
line.
