46 Tempest®2400 2-Channel Wireless Intercom System
Call Funcon
There are two call methods available in Tempest. The rst uses the CALL buon to send call signals to any BeltStaon or
hard wired user on the acve channel. The second method is referred to as “Call On Talk” and uses the BeltStaon TALK
buon to iniate a call signal. However, the “Call On Talk” feature works independently from all other BaseStaon call
sengs and can be used to send call signals through intercom channels to aached radios or matrix.
To enable the CALL buon, press MENU, select “Set Controls,” select “Call Buon,” and select Enable. This is the default
seng.
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 vibraon of the BeltStaon or Both. The default seng is Both.
To iniate a call, select a channel for talking with the CH A or CH B buons and acvate the TALK buon. 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 Buons”, then “HW Call on Talk”, and
select Enable. The default seng is Disable.
Program Volume Control
Auxiliary IN can be used to bring program or other audio into the Tempest BaseStaon. Audio from the Aux IN port is routed
only to wireless users and is not routed out to the hard wired system.
Program Volume allows each BeltStaon to control the mix of program audio (Aux IN) it receives from the BaseStaon.
To enable “Program Volume”, press MENU, then “Set Controls”, then “Program Volume” and select one of three opons:
1. O - the BeltStaon receives no program audio.
2. Absolute - the BeltStaon receives program audio at a level independent of the intercom levels.
3. Relave - the BeltStaon receives program audio at a level relave to the maximum intercom volume seng, regardless of
channel. Scroll to the opon that applies to your applicaon and press ENTER to save. Your selecon will be indicated
with a check mark to the le of the selecon.
To adjust the Program Volume on the BeltStaon, hold the ENTER buon 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 buon is sent only when the Talk buon is
enabled, and only on the channel selected for Talk.
When “Relave” is selected, the program volume is relave to the highest
level intercom channel on the BeltStaon. 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).
