Transmitting And Receiving; Optional Functions (Via Programming Software); Squelch; Voice Operated Transmission (Vox) - Albrecht Tectalk Worker 3 Manual

6. Transmitting and receiving

When the radio is switched on, it is automatically in receive mode as
long as you are not transmitting. When a radio message is received, the
status indicator lights up green.
To transmit, press and hold the PTT (Push-to-Talk) button and speak into
the microphone at normal volume and about 5 cm distance. The status
indicator lights up red during transmission. Release the PTT button at the
end of your transmission.

7. Optional functions (via programming software)

The following options can be changed via programming software (not included, optionally available).
The preset values of the radios are:
• Squelch: level 3
• VOX: off
• Programmable button: monitor
• Battery saving mode: off
• Beep at end of reception: on
• Scrambler: off
• Roger Beep: off
• Transmit time limit: on (90 seconds)

7.1. Squelch

The squelch can be set to 9 different levels.
The squelch mutes the speaker when no signal is being received. If the squelch is set correctly, you
will only hear noise during reception. If the squelch is set too low, you will constantly hear a slight
hiss. If the level is set too high, weak radio transmissions are suppressed.

7.2. Voice Operated Transmission (VOX)

The VOX function allows you to send radio messages without having to press the PTT button. The
Tectalk Worker 3 automatically goes into transmission mode when the VOX function detects that
someone is speaking into the microphone.
The VOX sensitivity can be selected in 8 different levels: Level 1 means that VOX is activated at very
low noise levels. Level 8 means that you have to speak very loudly into the microphone to activate
VOX.
With the VOX delay, you set the time after which the automatic transmission mode is terminated
without speech. You can set the delay between 0.3 sec. and 3.0 sec.

7.3. Programmable key

The programmable side key of the Tactalk Worker 3 can be assigned to various functions.

7.3.1. Monitor

If you hold down the side button for a long time, the squelch is deactivated temporarily and you can
hear all signals including noise.
The monitor function is very useful when you want to adjust the volume or receive weak signals
(which would be suppressed by the squelch).
