Front Panel Right
The Front Panel Right controls 1 – 7, will normally be used together to configure the Tempest
BaseStation for 2-Wire or 4-Wire operation.
1- 2-Wire Intercom Type Slide Switch A&B/C&D
The two 2-Wire Intercom Type slide switches 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. The C&D switch selects the 2-Wire system type for both the C and the D intercom channels.
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.
2- Wired Intercom Channel Select (SEL) Button
The Intercom Channel Select (SEL) button is used to select one of the four 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 four Channel (CHAN) LEDs labeled A through D 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.

4- 2-Wire/4-Wire Select (SEL) Button
The 2-Wire/4-Wire Select (SEL) button sets the wired intercom mode for each of the four intercom channels. When a channel is selected with the CHAN SEL button, pressing the 2-Wire/4-Wire Select (SEL) button changes the selected intercom mode between 2-Wire, 4-Wire, or no connection.
5- 2-Wire/4-Wire LEDs
The eight 2-Wire/4-Wire LEDs indicate the currently selected intercom mode for each of the four intercom channels. If either a 2-Wire or 4-Wire connection has been enabled for a particular intercom channel, the corresponding 2-Wire or
4-Wire LED indicator will be illuminated. When no intercom has been enabled, the corresponding 2-Wire or 4-Wire LED indicators will be OFF.
6- IN Level Control
In Menu Mode, from the Intercom Levels screen, the IN control adjusts the incoming level of the currently selected wired intercom channel, from the hardwired intercom system to the Tempest BaseStation. If 2-Wire is selected, the IN Level control adjusts the incoming level of the 2-Wire signal. If 4-Wire is selected, the IN Level control adjusts the incoming level of the 4-Wire signal. If neither 2-Wire nor 4-Wire is selected, the IN Level control is inactive. In addition to the intercom IN levels, the IN control is used to adjust Aux IN levels.
7- OUT Level Control
In Menu Mode, from the Intercom Levels screen, the OUT level control adjusts the outgoing level of the currently selected wired intercom channel going to the hardwired intercom system from the Tempest BaseStation. If 2-Wire is selected, the
OUT Level control adjusts the outgoing level of the 2-Wire signal. If 4-Wire is selected, the OUT Level control adjusts the outgoing level of the 4-Wire signal. If neither 2-Wire nor 4-Wire is selected, the OUT Level control is inactive. In addition to the intercom OUT levels, the OUT control is used to adjust Aux OUT levels.
8- USB Connector
The USB connector is used to update the Tempest BaseStation firmware and is not used in normal operation.
9- Beltpack Program Connector
The Beltpack Program connector is used to pair the BaseStation with BeltStations. To pair the BaseStation with a particular
BeltStation, ensure that the BaseStation is powered ON and in Operational Mode (not in Menu Mode). Ensure that the
BeltStation is powered OFF. Plug one end of the pairing cable into the BaseStation, and plug the other end of the pairing cable into the BeltStation. Turn the BeltStation power ON by pressing and holding the BeltStation Power ON/OFF switch for two seconds. The pairing process happens automatically and the message “Pairing Complete” will appear on the BeltStation
LCD for approximately three seconds when done.
10- Power ON/OFF Switch
The ON/OFF switch is used to turn the BaseStation power (AC or DC) ON and OFF.
