Basic Intercom Key Operation
Receiving a Call from an Assigned Alpha
When a call comes into the beltpack from a keypanel assignment that already has a key assigned on the beltpack, the front
panel alpha starts flashing as well as the Talk LED button on the top panel that corresponds with the keypanel key in the front
panel display.
To answer a call from an assigned alpha, do the following:
> On the top panel of the beltpack, tap the flashing talk LED button.
NOTE: Audio is heard as soon as the Talk LED button starts flashing, even though the corresponding Talk LED
button has not been pressed.
Making a Call to an Assigned Alpha
To make a call, do the following:
> On the top panel of the beltpack, tap the Talk LED button that corresponds with the keypanel assignment
displayed in the front panel display screen.
A red talk bar appears on the talk assignment displayed in the front color display.
To release a call, do the following:
> On the top panel of the beltpack, tap the Talk LED button that corresponds with the alpha displayed in the front
panel display screen.
A red talk bar disappears from the talk assignment displayed in the front color display.
Receiving a Call from an Unassigned Alpha
Unassigned alphas are calls that have not been assigned a key on the beltpack. When a call comes to the beltpack from an
unassigned alpha, the assignment displays in the call waiting window and an audio chirp is heard in the headset.
For more information, see “Call Waiting Window” on page 85.
To receive a call from a non-assigned alpha, do the following:
> When a non-assigned alpha calls the beltpack, press and hold the reply button to answer.
As long as the button is held, the audio is heard by the non-assigned caller.
NOTE: Audio is heard as soon as the CWW displays the caller’s alpha.
IMPORTANT: All non-assigned calls and callers must use push-to-talk. Push-to-talk is done by pressing the Reply
button when wanting to talk.
To release a call from an unassigned alpha, do the following:
> When finished, press the Clear button on the top panel of the beltpack.
