1 Modem
The modem in the computer must be connected to an analog telephone line using a 6-pin, RJ-11 modem
cable (not included with the computer). In some countries, a country-specific modem cable adapter is
also required. Jacks for digital PBX systems may resemble analog telephone jacks, but they are not
compatible with the modem.
WARNING! Connecting the internal analog modem to a digital line can permanently damage
the modem. Immediately disconnect the modem cable if you accidentally connect it to a digital
line.
If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end (2) of the cable toward the computer.
NOTE The computer may look different from the illustrations in this guide. The location of the
modem jack varies by model.

Connecting a modem cable
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug
a modem cable (not included with the computer) into the RJ-45 (network) jack.
To connect a modem cable:
1. Plug the modem cable into the modem jack (1) on the computer.
2. Plug the modem cable into the RJ-11 telephone wall jack (2).
2 Chapter 1 Modem ENWW

Connecting a country-specific modem cable adapter
Telephone jacks vary by country. To use the modem and the modem cable (not included with the
computer) outside the country in which you purchased the computer, you must obtain a country-specific
modem cable adapter.
To connect the modem to an analog telephone line that does not have an RJ-11 telephone jack:
1. Plug the modem cable into the modem jack (1) on the computer.
2. Plug the modem cable into the country-specific modem cable adapter (2).
3. Plug the country-specific modem cable adapter (3) into the telephone wall jack.

Viewing the current country selection

1. Select Start > Control Panel.
2. Click Clock, Language, and Region.
3. Click Regional and Language Options.
4. Under Location, view your present location.
4 Chapter 1 Modem ENWW

Adding new locations when traveling
By default, the only location setting available to the modem is a location setting for the country in which
you purchased the computer. As you travel to different countries, set the internal modem to a location
setting that meets the operating standards of the country in which you are using the modem.
As you add new location settings, they are saved by the computer so that you can switch among settings
at any time. You can add multiple location settings for any country.
CAUTION To prevent losing your home country settings, do not delete your current modem
country settings. To enable modem use in other countries while preserving your home country
configuration, add a new configuration for each location in which you will use the modem.
CAUTION To prevent configuring the modem in a way that violates the telecommunications
regulations and laws of the country you are visiting, select the country in which the computer is
located. The modem may not function properly if the correct country selection is not made.
To add a location setting for the modem:
1. Select Start > Control Panel > Hardware and Sound > Phone and Modem Options.
2. On the Dialing Rules tab, click New. (The New Location window is displayed.)
3. In the Location name box, type a name (home, work, etc.) for the new location setting.
4. Click a country or region from the Country/region drop-down list. (If you select a country or region
that is not supported by the modem, the Country/region selection for USA or UK is displayed by
default.)
5. Enter the area code, a carrier code (if necessary), and the number to access an outside line (if
necessary).
6. Next to Dial using, click Tone or Pulse.
7. Click OK to save your new location setting. (The Dialing Rules window is displayed.) Then
●To set your new location setting as the current location, click OK.
●To select another location setting as the current location setting, click your preference from
the settings in the Location list, and then click OK.
NOTE You can use the preceding procedure to add location settings for places within your
own country as well as in other countries. For example, you could add a setting named
“Work” that includes dialing rules for accessing an outside line.

Solving travel connection problems
If you experience modem connection problems when using the computer outside of the country in which
you purchased it, try the following suggestions.
●Check the telephone line type.
The modem requires an analog, not a digital, telephone line. A line described as a PBX line is
usually a digital line. A telephone line described as a data line, fax machine line, modem line, or
standard telephone line is usually an analog line.
●Check for pulse or tone dialing.
An analog telephone line supports one of 2 dialing modes: pulse dialing or tone dialing. These
dialing mode options are selected in the Phone and Modem Options settings. The dialing mode
option selected must match the dialing mode supported by the telephone line in your location.
To determine the dialing mode supported by a telephone line, dial a few digits on the telephone,
and then listen for clicks (pulses) or tones. Clicks indicate that the telephone line supports pulse
dialing. Tones indicate that the telephone line supports tone dialing.
To change the dialing mode in your current modem location setting:
a. Select Start > Control Panel > Hardware and Sound > Phone and Modem Options.
b. Click the Dialing Rules tab.
c. Select your modem location setting.
d. Click Edit.
e. Click either Tone or Pulse.
f. Click OK twice.
●Check the telephone number you are dialing and the response of the remote modem.
Dial a telephone number, make sure there is a response from the remote modem, and then hang
up.
●Set the modem to ignore dial tones.
If the modem receives a dial tone it does not recognize, it does not dial and displays a “No Dial
Tone” error message.
To set the modem to ignore all dial tones before dialing:
a. Select Start > Control Panel > Hardware and Sound > Phone and Modem Options.
b. Click the Modems tab.
c. Click the listing for the modem.
d. Click Properties.
e. Click Modem.
f. Clear the check box for Wait for dial tone before dialing.
g. Click OK twice.
6 Chapter 1 Modem ENWW

If you continue to receive the “No Dial Tone” error message after clearing the Wait for dial tone before
dialing check box:
1. Select Start > Control Panel > Hardware and Sound > Phone and Modem Options.
2. Click the Dialing Rules tab.
3. Select your current modem location setting.
4. Click Edit.
5. Select your current location from the Country/region drop-down list, and enter the area code in
the Area code box. If you select a country or region that is not supported by the modem, the Country/
region selection for USA or UK is displayed by default.
6. Click Apply and then OK.
7. In the Phone and Modem Options window, click the Modems tab.
8. Click the listing for the modem, and then click Properties.
9. Click Modem.
10. Clear the check box for Wait for dial tone before dialing.
11. Click OK twice.

2 Local area networks
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (not included with the
computer). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the computer.
NOTE The computer may look different from the illustrations in this guide. The location of the
network jack varies by model.
To connect the network cable:
1. Plug the network cable into the network jack (1) on the computer.
8 Chapter 2 Local area networks ENWW

2. Plug the other end of the cable into a network wall jack (2).
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not
plug a modem or telephone cable into the RJ-45 (network) jack.
