Line Buttons

The 10 or more buttons in the center of your phone are line buttons (they connect you to lines in the system). The MLX-10D phone has 10 buttons, the MLX20L phone has 20 buttons, and the MLX-28D phone has 28 buttons. Use these buttons to make inside calls (to and from other extensions) and outside calls.

Two or more line buttons are labeled either ICOM (Intercom) or SA (System Access). You have either ICOM or SA buttons, but never both.

If you have ICOM buttons, use them for inside calls only. Use buttons labeled with phone numbers for outside calls.

If you have SA buttons, use them for both inside and outside calls. You must enter a dial-out code (usually a 9) to make an outside call on an SA button.

You can program a feature onto any unlabeled line buttons. See Chapter 3 for more on programming unlabeled line buttons.

Depending on your company, you mayor may not have all the buttons described next. If your phone has SA buttons, turn

to page 1-20.If your phone has ICOM buttons, turn to page 1-22.
