Troubleshooting Your Computer
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 using fax Class 2 in the fax software, try using Class 1.
• Close any other communications programs.
• 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.
