5.5 Monitor

The MON (monitor) button is mainly useful for two purposes:
• If the channel you have tuned has been programmed in the Open
Traffic mode, briefly pressing the MON button temporarily disables
the squelch in order to allow you the reception of extremely weak
signals that can't steadily open the squelch and are therefore recei-
ved "chopped".
• If the channel you have tuned has been programmed with
CTCSS/DCS and/or Selective Call, a brief pressure of the MON but-
ton temporarily disables the CTCSS/DCS and/or Selective Call to
allow you to monitor all the communications on the tuned channel,
even the ones that are not belonging to your network. Practically, you
are able to temporarily receive in Open Traffic just briefly pressing the
MON button.
In any case, if the MON button is enabled on your transceiver, press
it briefly to temporarily monitor the signals on the tuned channel and
repeat this operation to return to the normal condition.
Every time the MON button is pressed, a high or low acoustic tone will
be produced to notify respectively the monitor function enabled (open
squelch or disabled CSCSS/selective call) or disabled (closed squelch
or enabled CSCSS/selective call)
Depending on the programming, the MON button could not be acti-
ve or work in order to disable the CTCSS/DCS only or the selective
call only. Please refer to your dealer/radio network manager for details.
12 Basic operations

5.6 Transmission

To transmit please follow this procedure:
1) Ensure that the channel is not busy (otherwise you will create an inter-
ference), verifying that the status LED is not glowing green or amber.
If the channel is not free, please wait until that condition (LED turned
off)
2) Keep pressed the PTT button and verify that the status LED is glo-
wing red to show that you are transmitting.
3) Speak with a normal voice level at approximately 5-10 cm from the
microphone.
4) When your message is over, release the PTT button ensuring that the
status LED is turned off.
Don't shout! It won't increase the distance range, but rather will make
you heard distorted.
Don't release the PTT button before your message is over or start tal-
king before pressing it, otherwise your message will be "chopped"."
A handheld radio doesn't normally allow to talk and receive simulta-
neously, for this reason make your messages with a reasonable time.
When you are talking, the other parties can't do that, so don't occupy
too much the channel.
In order to transmit properly, please also see the following paragraphs.
5.6.a Time-out Transmission Timer (TOT)
The radio might be programmed with the internal TOT timer (Time Out
Timer) which automatically put your radio in reception if you talk too long
(after a preset time). In this case release the PTT button and wait for few
seconds: the radio TX features will be automatically restored. Ask the
network responsible or your dealer for further details.
