Albrecht Tectalk Duo - Radio Settings; VOX Function

25
English
7.1. Radio settings
In this submenu, you can change settings for sending and receiving radio messages.
7.1.1. Squelch (SQL)
The squelch can be set to 5 different levels.
The squelch mutes the speaker when no signal is being received. If the squelch is set correctly,
you will only hear noises 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 will be suppressed.
7.1.2. Busy Channel Lockout
When this function is activated, it is not possible to transmit on a channel if a sufciently strong
signal is already being received on this channel. This prevents accidental crosstalk, which
would make both radio transmissions unintelligible.
7.1.3. Time out timer
Here you can set a time after which a continuous radio message is automatically interrupted.
This can prevent unintentional continuous transmission.
7.1.4. Mic gain
You can set the microphone sensitivity here. A high sensitivity means that you have to speak
less loudly and with less discipline directly into the device, but it also picks up more background
noise. Reduce the microphone sensitivity in noisy environments.
7.1.5. Noise tail elimination
If the noise tail suppression function is active, the radio suppresses the noise that usually
occurs at the end of outgoing calls. We recommend leaving this function activated to increase
the comfort of the recipient. If you wish to signal the end of a transmission, use the next menu
item “Roger beep”.
7.1.6. Roger beep
With the Roger beep function, a signal tone is automatically played and transmitted when the
PTT button is released, signaling the end of the radio conversation to both parties.
7.2. VOX function
The VOX function (voice operated exchange) is a hands-free system. If it is activated, the
device transmits automatically once you speak into the microphone without you having to
press the PTT button.
7.2.1. VOX switch
The VOX function can be switched on and off here.
7.2.2. VOX sensitivity
A higher VOX sensitivity means that voice transmission is triggered at a lower voice volume,
but can more easily lead to continuous transmission in noisy environments.
7.2.3. VOX delay
The VOX delay species how long you have to interrupt speaking before the transmission
is stopped. A short delay ensures that the VOX function reacts more quickly, but can lead to
unwanted interruptions in the transmission.
