Ringing Patterns

System phones have these ringing patterns:

■An outside call will ring . . . ring . . . ring.

■An intercom call will ring BEEP . . . ring BEEP. . . ring BEEP. If you have a system display phone, the caller’s extension number (and name if programmed) will show on the display.

■A transferred call, or an unanswered transferred call that is ringing back at your extension, will ring BEEP BEEP. . . ring BEEP BEEP. . . ring BEEP BEEP.

NOTE:

If you use the system with PBX or Centrex lines, the PBX/Centrex distinctive ringing patterns are not passed to phones. Phones use the ringing patterns described here instead.

Dial Tones

You will encounter two different dial tones when calling with a system phone:

■Outside dial tone is generated by your local phone company to indicate that you are connected with an outside line.

■Intercom dial tone is generated by the system to indicate that you are connected with an inside line. You hear this dial tone when you are making an inside, or intercom, call.

To hear the difference between the two types of dial tones on a system phone, press a line button. The dial tone you hear is an outside dial tone. To hear an intercom dial tone, press [ Intercom ].

Using the Handset Speaker, and Microphone

Every system phone (except the MLC-6 phone) has a speaker, which you can turn on by pressing [ Spkr ]. When the green light next to [ Spkr ] is on, the speaker is on.

MLS-34D, MLS-18D, MLS-12D, and MLS-12 phones also have a microphone. On these phones, pressing [ Spkr ] turns on both the speaker and the microphone. In addition, you can turn just the microphone on and off by pressing [ Mic ]. When the green light next to [ Mic ] is on, the microphone is on.
