Special Restrictions in Certain Countries

■
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 to country. Check with your
telephone company.
■
When you use a modem, an external surge protector can
prevent notebook damage by lightning or other electrical
surges. Connect any approved surge protector to the modem
cable whenever you are using the modem.

Changing Your Modem Settings

The modem is already set up to be compatible with telephone
systems and modems in most areas. However, in some situations,
you might have to change modem settings to match local
conditions. If you have questions about local requirements,
contact your telephone company.
