Instruction manual

Features
The principal extension or a Shared SA button can be used to join a
conversation in progress. A maximum of three parties can participate in one
call.
NOTE:
Shared SA buttons cannot be assigned to single-line telephones or other
tip/ring equipment connected to an 012 or 008 OPT module. Shared SA
buttons can be assigned to a tip/ring or external alert device connected to
an MFM in an MLX telephone.
ICOM Buttons —
Key and Behind Switch Modes
In Key mode and Behind Switch mode, telephones have ICOM buttons, which
are used as follows:
■ To dial the Idle Line Access code (usually 9) to select the first idle
Personal Line assigned to the telephone (Key mode only)
■ To make an inside call
■ To activate a feature by using a feature code
■ To receive inside calls, including voice-announced calls, and transferred
outside calls
An ICOM button can have one of three attributes:
Ring Button is used to make inside ringing calls, to receive inside
and transferred outside calls, and to dial the Idle Line
Access code to select a Personal Line.
Voice Button is used to make inside voice-announced calls, to
receive inside ringing calls, and to dial the Idle Line Access
code to select a Personal Line. If the person receiving an
inside call made from this button has a speakerphone and it
is not already in use or disabled by having Voice Announce
to Busy turned off, the call arrives on the speakerphone.
Both parties hear a beep and the called person hears the
caller’s voice over the speakerphone. Since voice-
announced calls cannot be made to single-line telephones,
a call made on this button to a single-line telephone is a
ringing call even if the single-line telephone has a
speakerphone.
Originate Only
Button is used only to make inside calls. Calls are not
ordinarily received on this button. Its purpose is to ensure
that the user always has a button available to make or
transfer calls, establish conference calls, answer Call
Waiting calls, or pick up parked calls. The button can be
programmed for either Ring or Voice operation.
