Using A Projector Or External Display; Changing Display Settings - Lenovo ThinkPad T420 User Manual

Dialing manually
If your computer is repeatedly unable to connect to your ISP or to a LAN, it is easier to dial an access number
manually. For details, refer to your Windows online help.
Note: You will need to have a dual jack to the same phone line or a "Y" splitter for your phone line so that
your computer and your telephone can share a line.
Modem use abroad
Different countries and regions follow different procedures and regulations regarding modem use. Be sure to
check with your hotel front desk or with the local telephone utility to learn the proper procedure for plugging
in and unplugging your modem and power cord.
DANGER
To avoid shock hazard, do not connect the cable to or disconnect the cable from the telephone
outlet on the wall during electrical storms.
Around the world there are dozens of plugs and jacks for phone connections. You can usually purchase an
adapter while in destination country, but adapter kits are available in your home country prior to your trip.
Some countries support pulse dialing rather than tone dialing. To change dialing methods, refer to your
Windows online help.
Note: In many regions, you cannot use the built-in modem function until Lenovo has received approval from
the proper authorities.
Your built-in modem is a worldwide modem and can be used in any region where Postal Telegraph and
Telephone (PTT) type approval has been obtained. You can change the modem setting as needed for
the region where you use the modem.
For more information on the use of the built-in modem in a specific region, contact the Customer Support
Center in that region.
