Your MLX-10 Telephone
SA Originate Only. Use this button only to make calls; calls
do not come in on this button. To make an outside call, enter
a dial-out code (usually a 9) before dialing the phone number.
This button is set up by your company to make either inside
ringing or voice-announced calls (not both).
Shared SA. Use this button to answer calls for co-workers
and to join their conversations. Each button is linked to a
specific SA button on a co-worker's phone. Shared SA
buttons are labeled either Shared SA Ring or
Shared SA Voice, depending on which type of inside calls
the button allows you to make. You can use these buttons to
make and receive inside and outside calls, just like your own
SA Voice and SA Ring buttons. These buttons are set up by
your company.
555-1234. Use any button labeled with a phone number to
make or receive outside calls only. It is a direct outside line
that does not need a dial-out code.
Pool. Use this button to get an outside line from a group of
outside lines. You may have a different label on one or more
of these buttons, or you may need to enter a dial-out code (or
pool code). Consult your system manager for an explanation
of their purpose and use.
