46 Tempest®24 00 4-Channel Wireless Intercom System
Call Func on
There are two call methods available in Tempest. The rst uses the CALL bu on to send call signals to any BeltSta on or
hardwired user on the ac ve channel. The second method is referred to as “Call On Talk” and uses the BeltSta on TALK
bu on to ini ate a call signal. However, the “Call On Talk” feature works independently from all other BaseSta on call
se ngs and can be used to send call signals through intercom channels to a ached radios or matrix.
To enable the CALL bu on, press MENU, select “Set Controls,” select “Call Bu on,” and select
Enable. This is the default
se ng.
To set the “Call Alert” preference, press MENU, select “Set Controls,” and select “Call Alert.” Choose to receive a call signal
alert with an
Audible tone in the headset, or with a vibra on of the BeltSta on or Both. The default se ng is Both.
To ini ate a call, select a channel for talking with the CH A/B or CH C/D bu ons and ac vate the TALK bu on. Press and hold
CALL for as long as you want the call signal to go out on the channel. A call signal will be received by users who are listening
on the same channel that originates the call signal.
To enable the “Call on Talk” feature, press MENU, select “Set Controls”, then “Talk Bu ons”, then “HW Call on Talk”, and
select
Enable. The default se ng is Disable.
Program Volume Control
Auxiliary IN can be used to bring program or other audio into the Tempest BaseSta on. Audio from the Aux IN port is routed
only to wireless users and is not routed out to the hardwired system.
Program Volume allows each BeltSta on to control the mix of program audio (Aux IN) it receives from the BaseSta on.
To enable “Program Volume”, press MENU, then “Set Controls”, then “Program Volume” and select one of three op ons:
1. O - the BeltSta on receives no program audio.
2. Absolute - the BeltSta on receives program audio at a level independent of the intercom levels.
3. Rela ve - the BeltSta on receives program audio at a level rela ve to the maximum intercom volume se ng, regardless of
channel.
Scroll to the op on that applies to your applica on and press ENTER to save. Your selec on will be indicated
with a checkmark to the le of the selec on.
To adjust the Program Volume on the BeltSta on, hold the ENTER bu on and then turn either of the volume knobs. The
display screen will display “Program Vol” and the numeric level of the volume.
A call signal from the CALL bu on is sent only when the Talk bu on is
enabled, and only on the channel selected for Talk.
When “Rela ve” is selected, the program volume is rela ve to the highest
level intercom channel on the BeltSta on. Thus, when listening to program
audio when intercom volume on channel A was at 15 and channel C was at
10, the program volume would be 15. If that intercom level is lowered
below 10, then your new program volume would then correspond to
channel C’s volume level (10).
