Your MLX-10 Telephone
Line Buttons
There are ten line buttons—two columns of five each—in the
center of the phone. Use these buttons to make and receive
inside calls (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 button.
See Chapter 3 for more on programming unlabeled line
buttons.
Depending on your company, you may or may not have all the
buttons described next. If your phone has SA buttons, turn to
page 1-7. If your phone has ICOM buttons, turn to page 1-9.
