Q
I cannot hear the modem sound.
A1 Check that the telephone line is properly connected
to the modem.
A2 Check that the modem driver is installed properly.
 Click Start > Control Panel > Performance
and Maintenance > System.
 Select Hardware tab > Device Manager >
Modems in the System Properties window,
and check if there is a yellow exclamation mark
on the installed modem icon. If there is, delete
the modem device driver and reinstall the
driver, because the yellow exclamation mark
represents a not properly installed driver.
 If there is no yellow exclamation mark, double-
click the installed modem, and click Diagnostics
tab > Query Modem in the Modem Properties
window to diagnose the modem.
No message in either of Command and Response
in the Diagnostics tab means that the modem is not
operating properly.
Diagnose the modem again after restarting the
system or reinstalling the driver.
(You have to exit all programs using modem in the
advance of diagnostics of the modem).
Q
I cannot make a call using an extension line.
A In general, the dial tone of a PBX or a digital phone
switching system is not a continuous one, unlike that
of a trunk line.
Therefore, the modem may not make a call because
the modem mistakes the dial tone from a PBX or a
digital phone switching system as a busy tone. In this
case, complete the following procedures.
▶ Using an AT command
As an initialization command, use the command,
ATX3. Otherwise, enter the ATX3 command
manually before making a call.
It can correct this problem by skipping the dial tone
check step.
▶ Configuring the Modem through the Control
Panel
 Click Start > Control Panel > Network and
Internet Connections.
 Under See Also, click Phone and Modem
Options.
 In the Modems tab, select the installed modem,
and click Properties.
 In the Modem tab of the Modem Properties
window, clear the "Wait for dial tone before
dialing" check box.
 When the configuration is completed, click OK.
