NOTE:
The tone you select will be used for all channels that
have 'Silent' enabled.
Enabling CTCSS/DCS on a channel (Silent mode)
Enabling CTCSS/DCS on a channel will prevent the Squelch
from opening on that channel unless the incoming signal
matches your selected CTCSS/DCS tone. Other users on the
same channel who are not using your CTCSS/DCS tone will
still be received by your radio (the
the display) – but their voice will not be heard in the speaker.
Only when someone transmits on the channel using your
CTCSS/DCS tone will the Squelch open to allow the signal to
be heard. Channels where CTCSS/DCS have been enabled are
said to be in 'Silent mode'.
NOTE: Silent mode can be enabled on any channel except
emergency channels 5 and 35.
To enable Silent Mode on a channel
1. Select the required channel.
2. Press and hold the
3. An icon (CTCSS) or

NOTE:
You cannot enable Silent mode unless a CTCSS or DCS
tone has been selected in the Configuration Menu. If CTCSS/
DCS has been set to OFF, Silent mode is inhibited.

Silent mode has been removed from that channel.
IMPORTANT: When Silent mode is enabled on a channel
you should always check the
channel before transmitting to ensure you do not accidentally
transmit over the top of another user.

MONITORING THE CHANNEL

It is useful to be able to temporarily open your radio's Squelch
to allow you to listen for signals from other CTCSS/DCS
users outside your group. Because their CTCSS/DCS tone is
different to yours, your Squelch would normally remain closed,
preventing you from hearing them. You can use the
to open the Squelch and listen to the channel to check that
it is clear before transmitting. This will help prevent you from
accidentally transmitting over the top of others.
To monitor the channel
Briefly press the key. If there are no signals present, you
will hear the usual hiss of an empty channel. Press the
key again to restore the Squelch to its previous setting.

SCANNING

The TX3350 has a SCAN function that allows groups of user
programmable channels to be scanned for signals. Channels
can be scanned at 20 channels per second. When a signal is
found, scanning will pause on that channel to allow the signal
to be heard, then resume scanning when the channel is
clear again.

SCAN GROUPS

The TX3350 features two scan groups by default – Open Scan
and Group Scan.
