If the modem dials but you can’t hear it 
•  Make sure the audio-off light is turned off. If it’s on, press the audio-off button. 
•  Check the speaker volume setting. 
•   In Control Panel, open Modems (Windows ME, 95 or 98) or Phone And Modem 
Options (Windows 2000). Select the modem and click Properties, then check the 
volume setting on the General tab. 
If the modem connects, but transferred data is bad 
•   In Control Panel, open Modems (Windows ME, 95 or 98) or Phone And Modem 
Options (Windows 2000). Make sure the parity, speed, word length, and stop bits 
match on sending and receiving modems. 
•  Try disabling error correction and data compression. 
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 doesn’t fax

•  If you’re faxing by printing from an application, make sure you’ve selected the fax 
printer. 
•  Try turning off power management features temporarily. 
If excessive line current is detected 
•  Make sure you’re 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.
