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.
For example, if you are dialing from Italy and fail to connect
to your server or cancel the connection, you must wait
1 minute before dialing that number again. If you dial before
then, you will get the message “delay.” After the fourth failed
connection, you must wait 1 hour before trying the number
again. If you dial before the hour is up, you will get the
message “black list.”
■ When using 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.
