CONNECTING THE BELTPACK TO THE SYSTEM
BASIC OPERATION
DETAILED OPERATION OF CONTROLS
Page 1
BP511 and BP531
This single circuit beltpack is connected to the system via the available male and female XLR 3 pin
connectors. By convention the female connector is used as the input and the male connector as the output
enabling the cabling to be 'looped through' to the next station, if required.
BP523 and BP543
This dual circuit beltpack is connected to the system via two 3 pin, female, XLR type connectors.
They are marked Circuit I and Circuit II. There is no ‘loop through’ capability.
BP525 and BP545
This dual circuit beltpack is connected to the system via male and female, XLR 5 pin connectors.
By convention the female connector is used as the input and the male connector as the output, enabling the
wiring to be ‘looped through’ to the next station, if required.
Headset operation
A Tecpro compatible headset, wired as in diagram 1or 2 (as appropriate), should be plugged into the 4 pin
XLR connector on the rear of the station.
Located on the front panel, the “MIC” button activates the headset mic to speak to the system when
depressed. The thumb operated 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
recessed side-tone control on the front 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, headphone volume and side-tone adjust control(s).
Microphone Select
Press the “MIC” button briefly and it will illuminate green.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 extin-
guish.
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 red for approximately two seconds.
During this time, briefly press the appropriate “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 green LED’s - bright.
3. Vibration mode ON/OFF (Duplicates Call LED and will respond to a Call signal when the Call LED is
suppressed in ‘dim’ mode) - default is ON.
4. Disable or enable mic 1 (Mic 2) - ENABLED.
Preference Settings
Alert Tone
Switch off mic 1 and 2, hold down “Call” button for 3 seconds - red call LED flashes slowly for 2 secs.
To select alert tone off, while Call LED is flashing, press mic 1 - call alert tone on for 1 sec.
To select alert tone on, while Call LED is flashing, press mic 1 - call alert tone on for 1 sec.
When the call alert mode is programmed ON, 50mS of call alert tone acknowledges that the call switch is
pressed at the start of the 3 sec ‘hold down’.This button press acknowledgement is then suppressed until the
unit deselects set up mode and reverts to normal operation.
LED Brightness
Switch off mic 1 and 2, hold down “Call” button for 3 seconds - red call LED flashes slowly for 2 sec.
To select dim LEDS, while call LED is flashing, press mic 2 - call LEDs on dim for 1 sec.
To select bright LEDS, while call LED is flashing, press mic 2 - call LEDs on bright for 1 sec.
Vibration ON/OFF - BP531, BP543 and BP545 only
Switch off mic 1 and 2, hold down call for 3 sec - red call LED flashes slowly for 2 sec.
To select vibration off, while call LED is flashing, press mic 1 and mic 2 – unit vibrates for 1 sec.
To select vibration on, while call LED is flashing, press mic 1 and mic 2 - unit vibrates for 1 sec.
Mic Disable
Switch off mic 1 and 2, hold down call for 10 sec - red call LED flash rate changes to quick flash after 10 sec.
To disable Mic 1, while call LED is flashing, press mic 1 - Mic 1 LED flashes once.
To enable Mic 1, while call LED is flashing, press mic 1 - Mic 1 LED flashes 3 times.
To disable Mic 2, while call LED is flashing, press mic 2 - Mic 2 LED flashes once.
To enable Mic 2, while call LED is flashing, press mic 2 - Mic 2 LED flashes 3 times.
PROGRAMMABLE OPTIONS

Circuit Enable/Disable
BP523 and BP543
If only one circuit is connected, then only this circuit is active. On the unused circuit, the line amplifier is dis-
abled and the Mic LED does not light if the Mic key is pressed.
BP525 and BP545
With XLR-5 connectors, a given circuit is only active if its +24 volt line is powered.
Mic Disable
If no headset is connected, the Mic functions will be disabled.This will prevent immediate feedback if the
headset is re-connected with the volume control on maximum but the headset not being worn.
