The modem is not recognized by your 

computer

•

Make sure that the line connected to the 

modem is working and plugged into the 

appropriate port on your computer. See 

your setup poster to make sure that the 

connections have been made correctly.

•

If the modem shares the telephone line 

with another device, make sure that the 

telephone line is not in use (for example, 

someone is on the telephone, or another 

modem is in use).

•

Use the modem cable that came with 

your computer. Some telephone cables 

do not meet cable standards and may 

cause problems with the connection.

•

Shut down and restart your computer.

•

Run Windows modem diagnostics.

The modem is noisy when it dials and connects
When your modem tries to connect to another 

modem, it begins 

handshaking

. Handshaking 

is a digital “getting acquainted” conversation 

between the two modems that establishes 

connection speeds and communication 

protocols. You may hear unusual handshaking 

sounds when the modems first connect. If the 

handshaking sounds are too loud, you can turn 

down the modem volume.

Monitor

The screen resolution is not correct

•

Change the screen resolution from the 

Display Settings 

dialog box.

The computer is running but there is no picture

•

Make sure that the monitor is plugged in 

and turned on. If the monitor is turned 

on, the power LED should be lit.

•

Adjust the brightness and contrast 

controls to the center position.
