Tempest900 2-Channel Operating Manual
Call Function
There are two call methods available in Tempest. The rst uses the CALL button to send call signals to any BeltStation or hard wired user on
the active channel. The second method is referred to as “Call On Talk” and uses the BeltStation TALK button to initiate a call signal. However,
the “Call On Talk” feature works independently from all other BaseStation call settings and can be used to send call signals through intercom
channels to attached radios or matrix.
To enable the CALL button, press MENU, select “Set Controls,” select “Call Button,” and select Enable. This is the default setting.
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 vibration of the BeltStation or Both. The default setting is Both.
To initiate a call, select a channel for talking with the CH A or CH B buttons and activate the TALK button. 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 Buttons”, then “HW Call on Talk”, and select Enable. The
default setting is Disable.
Program Volume Control
Auxiliary IN can be used to bring program or other audio into the Tempest BaseStation. 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 BeltStation to control the mix of program audio (Aux IN) it receives from the BaseStation.
To enable “Program Volume”, press MENU, then “Set Controls”, then “Program Volume” and select one of three options:
1. Off - the BeltStation receives no program audio.
2. Absolute - the BeltStation receives program audio at a level independent of the intercom levels.
3. Relative - the BeltStation receives program audio at a level relative to the maximum intercom volume setting, regardless of channel. Scroll to
the option that applies to your application and press ENTER to save. Your selection will be indicated with a check mark to the left of the
selection.
4. To adjust the Program Volume on the BeltStation, hold the ENTER button 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 button is sent only when the Talk button is enabled, and only
on the channel selected for Talk.
When “Relative” is selected, the program volume is relative to the highest level intercom
channel on the BeltStation. 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).
