Sending audio signal
By pressing rapidly the PTT button twice, you will send an audio signal to
other users on the same channel.

Following functions can be selected by pressing the “menu” button:
• VOX

VOX function and its sensitivity
The VOX function lets you open the transmission by voice without the
use of the PTT button. To get the most use from the VOX feature you
must first determine what sensitivity (noise level) is needed to activate
the VOX.
Push the “menu” button for three times; ‘VOX’ blinks on the display. Se-
lect the desired VOX level (HI or LO) by means of the p/q buttons and
then press the PTT button to confirm.
VOX can be adjusted in 2 positions:
• HI: high sensitivity (normal voice with no background noise)
• LO: low sensitivity (useful in very noisy areas or if you talk loudly)
To disable the VOX mode
Press the “menu” button for three times. ‘VOX’ blinks on the display. Se-
lect ‘OF’ by means of the p/q buttons and then push PTT to confirm.
Attention
To use the VOX with the headset provided with the M99-S model, move
the small switch of the headset to the VOX position. Move it back to PTT
position if you don’t use the VOX function.
Roger Beep: end transmission tone
When PTT is released the radio will beep to confirm to other users that
your transmission has finished. This feature is enabled by default and it is
displayed with the icon.
