Features
This single circuit wall station is connected to the system via
the available screw terminal connector PL1. (See diagram 1)
Headset operation
A Tecpro compatible headset, wired as in diagram 2
(as appropriate), should be plugged into the 4 pin XLR
connector on the front of the station. Located on the front
panel, the “MIC” button activates the headset mic to speak
to the system when depressed. The volume control can be
adjusted for a comfortable listen level.
Side-tone adjustment
The level of user’s voice in the headset is called ‘side-tone’.
The required level can be set by adjusting the side-tone
control VR3 on the rear panel with a small screwdriver.
Signal light operation
The CALL pushbutton flashes a light in all outstations
connected to the circuit. It is used to attract the attention
of a user that has the headset removed or volume level
turned right down.
ClearCom Compatibility
Tecpro stations are completely compatible with Clear-
Com stations. Any Tecpro stations added to Clearcom will
function as their Clear-Com equivalents. However, Clear-
Com stations have a lower bridging impedance and will
degrade a Tecpro system slightly due to a reduction in side-
tone stability incurred when a Clear-Com outstation is used
in a Tecpro communications system. The front panel houses
the mic select and call buttons and headphone volume.
Microphone Select
Press the “MIC” button briefly and it will illuminate Red.
This action switches on the mic circuitry and allows
the operation of other functions. To switch off the mic
circuitry press the “MIC” button briefly again. The lamp
within the button will extinguish. Holding the “MIC” button
continuously keeps the mic circuitry alive for the duration
of the press.
Call send
Ensure that a “MIC” circuit has been selected and that its
associated lamp is illuminated. Press the “CALL” button
briefly. This will cause the lamps on all other beltpacks on
the same circuit to flash for approximately one second. The
button will also illuminate red. A tone of similar duration will
sound in the headphones.
Remote Mic Kill send
Ensure mic circuits have been de-selected.
Depress the “CALL” button briefly three times. It will
illuminate for approximately two seconds. During this time,
briefly press the “MIC” button to switch off all mics on
that circuit.
All settings revert to default when power is removed
Default settings
1. Call alert tone ON/OFF - ON.
2. Bright or dim LED’s - bright.
3. Disable or enable mic - ENABLED.
