12.3
Ten fixed function keys surround the keypad. Two of these keys have LED visual
indicators. The fixed function keys are:
HOLD Key: Pressing the red Hold key places the current call on hard hold. The call
may-be retrieved by pressing the line select key of the call on hold (next to the flashing
line select status indicator).
,ME&AGE Key: The Message key is used to send a callback message to another
telephone set capable of receiving the message when that set is busy, unanswered,
or in Do Not Disturb mode. It is also used to initiate a return call to a telephone set that
has left a message.
MESSAGE Lamp: The red Message lamp is flashes when another telephone set has
left a callback message. The lamp lights (solid red) when the SUPERSET calls a
busy or unanswered party capable of receiving a message.
Pressing the message key
sends a message to the called set. After sending the message the lamp goes out and
the call is terminated.
SUPERKEY Key: The Superkey and the softkeys are used to program the Line
Appearance keys as Feature keys or Speed Call keys.
SPEAKER Key: The SPEAKER key controls handsfree operation of the set. Pressing
this key once switches the speaker ON and selects the prime line. Calls can be
originated and/or received handsfree. Successive operation of this key toggles the set
between ON/OFF hook states.
REDIAL Key: The last manually dialed number is dialed when the redial key is pressed.
CANCEL Key: This key is used to cancel a dialing sequence, end a call, terminate
without saving a programming function, or return to a par& on soft hold.
VOLUME/TONE UP and VOLUME/TONE DOWN Keys: These two keys are used to
adjust handset volume and ringing volume and tone.
Each key depression changes
s the level up or down by one step.
'The levels for ringing volume and pitch is stored in the PABX; changing one function
setting does not affect the others. On system or set resets, the levels are restored.
Default levels are applied when the set is first programmed. The handset receive level
is not reported to the PABX; therefore, on evev new call the default level is applied.
MICROPHONE Key and MICROPHONE Lamp: The microphone is turned on by the
system software when a handsfree call is activated. The Microphone key is used to
switch the microphone off during handsfree mode so that the conversation near the set
is not overheard
by the caller. Successive operation of the Microphone key toggles the
microphone between ON and OFF.
The Microphone lamp is lit (solid red) when the microphone is ON.
