Front Panel Right
1- 2-Wire Intercom Type Slide Switch A&B
The 2-Wire Intercom Type slide switch configure the BaseStation for the type of intercom that will be connected to the
corresponding 2-Wire connectors on the rear panel of the BaseStation. Clear-Com, RTS, or BAL (AudioCom) can be selected.
This switch only affects 2-Wire operation and not 4-Wire operation. The A&B switch selects the 2-Wire system type for both
the A and the B intercom channels.
2- Wired Intercom Channel Select (SEL) Button
The Intercom Channel Select (SEL) button is used to select one of the two intercom channels so that the intercom mode
-- 2-Wire or 4-Wire -- and audio input and output levels, may be adjusted.
Pressing the CHAN SEL button puts the BaseStation into Menu Mode and advances to the Intercom Levels screen.
Pressing the CHAN SEL button a second time selects channel A, for the opportunity to select 2-Wire or 4-Wire or no wired
connection, and IN and OUT levels can be adjusted (see 2-Wire/4-Wire Select below.)
Additional presses advance through the intercom channels, and return to Operational Mode. The intercom channel selected
is indicated by the two “CHAN” LEDs located to the immediate right of the SEL button.
Also, in the Aux IN/OUT menu, SEL advances through the channels to adjust the Aux IN and Aux OUT levels.
3- Channel (CHAN) LEDs
In Operational Mode, the two Channel (CHAN) LEDs labeled A and B are always illuminated.
Enter Menu Mode, by pressing the Channel Select (SEL) button ([2] above). In Menu Mode, the Channel LEDs indicate the
channel currently selected for adjustment. Only one channel may be selected at a time.
The Front Panel Right controls 1 – 7, will normally be used together to configure the Tempest
BaseStation for 2-Wire or 4-Wire operation.
Select the appropriate 2-Wire switch setting prior to connecting the 2-Wire intercom. Do not
switch between 2-Wire types while connected to a 2-Wire system and powered ON. The
different voltages in each system may damage equipment.
