Modem and Network Connections

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

one 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 one hour before trying the number again. If you dial before the hour is up, you will get the message “black list.”

■When your modem is in use, 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.
