duration of the call. The GN MIC key glows dim green whenever the
gooseneck microphone is present but off and bright green whenever
the microphone is present and on. If a gooseneck microphone is not
present, the GN MIC key will not illuminate. Table 2-1 summarizes the
key colors for active and non-active microphone and speaker keys.
TURNING THE HEADSET MICROPHONE ON AND
OFF
The headset microphone key, labeled “HS MIC”, turns your panel’s
headset microphone on and off. Press once to turn the microphone on;
press again to turn the microphone off.
When a headset is plugged in to the panel, the headset microphone
automatically becomes active and the gooseneck microphone is
switched off. To switch to the gooseneck microphone, press the
gooseneck microphone key, labeled “GN MIC.” When the headset is
unplugged, the gooseneck microphone automatically becomes active.
The HS MIC key glows dim green whenever a headset microphone is
present but off, and bright green whenever a headset microphone is
present and on. When a headset microphone is not present, the key
will not illuminate. Table 2-1 on page 7 summarizes the key colors for
active and non-active microphone and speaker keys.
TURNING THE SPEAKER ON AND OFF
The speaker on/off key, labeled “SPKR ON,” functions only when a
headset is plugged into the panel. Pressing the speaker on/off key
toggles the headset speaker on and off. Press the key once to turn the
headset speaker off, and again to turn the headset speaker back on.
As the headset speaker turns off, the panel speaker will turn on and
vice versa.
The key glows dim green whenever the headset speaker is off, and
bright green whenever the headset speaker is on.
Note: Unlike the microphones, both speakers can never be turned
off at the same time. The panel loudspeaker is always active
unless a headset or alternative speaker source has replaced
it. That is why this key is non-functional when a headset is
not plugged in.
USING THE “LISTEN” KEY TO ACCESS
FUNCTIONS
The LISTEN key has three functions:
• Activates the “monitor mode” of a “talk-with-listen” key
• Sends call signals
