Clear-Com i-Series Panels - Manual (Page 32)

5.4 Turning the speaker on and off
The speaker on/off key (SPKR ON) only functions when a headset is connected to the
panel.
Press the key once to turn the headset speaker off, and again to turn the headset speaker
back on.
Note:
When the headset speaker turns off, the panel speaker will turn on and vice versa.
The SPKR ON key is lit:
•
Dim green when the headset speaker is off.
•
Bright green when the headset speaker is on.
Unlike the microphones, you cannot turn off both speakers (the panel and the headset
speaker) at the same time. The panel loudspeaker is always active unless a headset or
alternative speaker source has replaced it.
Note:
The SPKR ON key is non-functional when a headset is not connected.
5.5 Using the Listen (LISTEN) key
You can use the Listen (LISTEN) key to:
• Place a talk-with-listen key in monitor mode.
• Send call signals.
• Release remote telephone lines.
