VOX (VOICE-OPERATED TRANSMISSION)
VOX eliminates the necessity of manually switching to
Transmit mode each time you want to transmit.
The transceiver automatically switches to Transmit mode
when the VOX circuitry senses that you have begun speaking
into the microphone.
When you operate the VOX function, you must use an optional
Headset; the internal speaker and microphone are too close to
each other to be used for the VOX function.
VOX On/ Off
1 Access Menu No. 150.
2 Select [On].
When VOX is activated, the gain level, and delay
•
time will appear on the display.
Note:
¡ While in Menu mode, the VOX function is temporarily disabled.
¡ Since the VOX circuit must detect the presence of your voice,
you may notice a slight delay in transmission; the very first part
of your message may not be transmitted.
¡ When the VOX function is ON, the ASC function turns OFF.
¡ VOX cannot be used with an optional Speaker/ Microphone.
VOX Gain
To enjoy the VOX function, take the time to properly adjust the
VOX Gain level. This level controls the VOX circuit to detect the
presence or absence of your voice.
There are 2 ways to adjust the VOX Gain.
While the VOX function is ON:
1 Speak into the headset microphone using your normal
tone of voice to transmit.
2 Adjust the VOX Gain by pressing [
transceiver reliably switches to transmission mode each
time you speak while the transceiver is transmitting.
