8.6 Call Signaling (PL Mode only)
Use Call Signaling to alert party line users that there is incoming audio on the line. By default,
call signaling uses the flashing call button to alert party line users. However, enabling call
alerts allows a beep or a vibration to signal incoming audio on the line. For more information
on call alerts, see
Call Alerts, page 79.
For example, a producer starts talking to a camera operator on PL01 and the camera operator
does not hear the producer because they are not wearing their headset. The producer can
send a call signal alert to PL01 that generates a call beep or vibration (if enabled) that would
let the camera operator know someone is talking and to put their headset on.
To send a call signal , do the following:
1. Press the talk keys you want to send the signal.
2. Press and hold, or latch on the talk keys for which you want to send the signal.
The red talk key indicators turn blue and the call signal icon shows in the center of the
display. The call signal generates for as long as you hold the CALL button, and the talk
keys are still on.
3. Release the CALL button , or turn off the talk keys to end the call signal.
Refer to
– Call Alerts, page 79
8.7 Talk and Listen
The Talk and Listen functions on the DBP act like any traditional keypanel.
Talk
There are four configurable modes of talk operation: Latching, Momentary, Always On, and
Always Off. For detailed descriptions about the modes of operation and how to configure Talk
operation, see
Setup | Key Modes, page 63.
To talk , do the following:
1. Press and hold, or latch on, the key with the assignment to which you want to talk.
2. Release the key , or tap it to unlatch it, to stop talking.
Listen
Listen key operation is the same as talk key operation, except that listen keys are always
latching and you need to press and hold the CALL/SHIFT button so that A - D key presses are
treated as listen key presses, not talk key presses.
Access to listen key states using the CALL/SHIFT button is only available in KP mode.
In PL mode, the listen keys are Always On (for PL assignments) and Always Off (for any other
type of assignment). For instruction on how to mute PL assignments on the belt pack, see
Volume adjustment, page 32.
To
listen , do the following:
1. Press and hold the CALL button .
2. Tap the key for which you want to change the listen key state.
