Considerations

The following instructions assume that system phones are set (using Automatic Line Selection) to automatically select outside lines first, and standard phones are set to select intercom first. This means that when a user with a system phone lifts the handset, the user hears outside dial tone (if an outside line is available); but when a user with a standard phone lifts the handset, the user hears intercom dial tone.

If you are using an MLC-6 cordless phone, make sure the handset is on before using the following instructions. Also, the MLC-6 phone has no speaker, so use the handset to make a call.

How to Make an Outside Call

System Phone

1.Lift the handset or press [ Spkr ].

The light next to the line button is steady green and you hear outside dial tone.

2.Dial the phone number.

On a system display phone, the dialed number appears on the display.

If you are using a PBX or Centrex line, you may also need to use a dial-out code (usually 9) before you dial a number outside the PBX or Centrex system.

To make an outside call on a specific line:

1.Press the idle (unlit) line button and lift the handset, or dial [ Intercom ] [ 8 ] plus the two-digit line number.

2.Dial the phone number.

To reserve a busy line (steady red light) so your phone beeps when the line becomes free—this is useful when you share a line, such as a WATS line, with other people:

1.Press the busy line button without lifting the handset or pressing [ Spkr ].

2.When the line is free and your phone beeps, lift the handset and dial the number. (If more than one person reserves a line, all their phones beep when the line is free. The first person to pick up the phone after the beep gets the line, and the other reservations are canceled.)

Standard Phone

1.Lift the handset.

You hear intercom dial tone.

2.Dial [ 9 ] to get an outside line. You hear outside line dial tone.

3.Dial the phone number.

If you are using a PBX or Centrex line, you may also need to use a dial-out code (usually 9) before you dial a number outside the PBX or Centrex system.
