CHAPTER 11: Troubleshooting

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.
To turn down the modem volume:
1 Click Start, then click Control Panel. The Control Panel window opens. If your Control
Panel is in Category View, click Printers and Other Hardware.
2 Click/Double-click the Phone and Modem Options icon, then click the Modems tab.
3 Click the modem you want to adjust, then click Properties.
4 Click the Modem tab, then adjust the Speaker volume control.
5 Click OK twice to close the Phone and Modem Options dialog box.

The color is not uniform
• Make sure that the monitor warms up for at least 30 minutes before making a final
judgment about color uniformity.
• Make sure that:
• Non-shielded speakers are not placed too close to the monitor.
• The monitor is not positioned too close to another monitor, electric fan, fluorescent
light, metal shelf, or laser printer.
• You demagnetize the screen using the monitor’s degauss feature. For more information
on degauss, see your monitor’s documentation.
