2 Restricted trafc mode does not guarantee privacy of
communication. Indeed, when using CTCSS/DCS, anyone
operating in open trafc mode can hear your conversation, they
cannot however take part, as they would not be heard from you.
2 Restricted trafc mode allows the use of the same radio frequency
by more than one group. For example, group A using CTCSS No.
16 tone will not hear conversations of group B who uses CTCSS
No. 20 tone and vice versa. However, if more than one user
transmits at the same time (e.g. one user from group A together
with one user from group B) on the same channel, there will be
interference. For this reason do not transmit if the radio signals
that the channel is busy even if you do not hear anything, waiting
instead for it to be free. If in doubt use the monitor function.
2 If you have to use MIDLAND G12 in the proximity of electrical
equipment which generates electrical noise causing the squelch
to open frequently, it is advisable that you use the restricted trafc
mode.
5.8 Monitor function

thecircuitwhichsilencesaudioreception(squelch)isautomatically
turned off as soon as you receive a signal. However extremely poor
signalsmaynottriggerittoswitchoffand,asaconsequenceofthis,
you will hear broken conversation. In this case the function monitor
will help by disabling temporarily the squelch.
Moreover if the channel you are using has been programmed to
operateinrestrictedtrafc(ref.par.5.7),withthefunctionmonitor
you can temporarily disable CTCSS or DCS in order to monitor all
communication on the channel you are tuned in.

2 Do not use the monitor function for too long as this will use up the
battery. The energy saving function (ref. par. 5.6.a) functions only
when the audio of your device is silenced (squelch enabled).
5.9 Selection of transmission power
The transmission phase absorbs the most energy. To extend the

2 If you are transmitting to someone who is nearby, try always low
power of transmission. In this way you will extend battery life
and reduce the risk of being heard by others outside your line of
communication.
