Using the Modem

3. Plug the other end of the phone cord into a telephone jack. If the plug on the phone
cord doesn’t fit the jack, you may need to use an adapter.
4. Check your modem’s country or region settings: click Start, Control Panel, Printers
and Other Hardware, Phone and Modem Options.
CAUTION
Your built-in modem may not work with multiple phone lines or a private branch
exchange (PBX), cannot be connected to a coin-operated telephone, and does not
work with party lines. Some of these connections may result in excess electrical
voltage and could cause a malfunction in the internal modem. Check your
telephone line type prior to connecting your phone line.
Special restrictions in certain countries
• The pulse dialing feature may be disabled in certain countries, possibly because Loop
Disconnect is not certified there. If pulse dialing is disabled, you should use tone
dialing connections only.
• Many countries impose a blackout period after a modem repeatedly fails to connect to
a service provider. The number of failed attempts and the period you must wait before
trying again differ from country/region to country/region: check with your telephone
company.
For example, if you are dialing from Italy and fail to connect to your server or cancel
the connection, you must wait one minute before dialing that number again. If you
dial before then, you will get an error message that says “delay.” After the fourth
failed connection, you must wait one hour before trying the number again. If you dial
before the hour is up, you will get a message that says “black list.”
• When using a modem in the Republic of South Africa, an external surge protector
may be necessary in order to prevent notebook damage by lightning or other electrical
surges. Connect any approved surge protector to the modem cable whenever you are
using the modem.
