appears on the display but you can’t hear a transmission, this
means that someone is transmitting on the same channel but is
using a different CTCSS code.
Using VOX mode
In VOX mode, your handset will automatically start to transmit
when it detects your voice (or other noise), without the
PTT
button pressed. It will then transmit for at least 2 seconds, even if
you stop talking before 2 seconds have passed.
There are three levels of VOX sensitivity — 1, 2 and 3. Level 1 is the
most sensitive, meaning that the handset will pick up softer noises;
at Level 3, it will pick up only quite loud noises.

If you set the VOX sensitivity to 0, you turn off VOX mode
altogether (this is the default).

Note
The VOX function will be temporarily disabled while you’re
transmitting, receiving, scanning, monitoring or programming the
handset.
Monitoring the current channel
The MR600 Twin has what’s called an
automatic squelch circuit
,
which turns the speaker off when no-one’s transmitting a message
to you. But if a transmission is weak, the circuit may prevent your
handset picking up the signal.
So you can temporarily de-activate (turn off) the circuit if you wish,
putting the handset into
monitor mode
, as follows:
◗
Press and hold
( (MONITOR, on the side of the handset)
After 1 second, your handset will pick up any signals on the current
channel, including any background noise.
◗
To stop monitoring, simply release
(Note that you cannot use ‘monitor mode’ while you are scanning
channels.)
