'silEnt' will disappear from the display.

you will not be able to activate ctcss/dcs if the ctcss/
dcs tone is set to 'oF'.

pages 19 and 20.

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 SQL key 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 SQL key. if there are no signals present, you will
hear the usual hiss of an empty channel. Press the SQL key again
to restore the squelch to its previous setting.

SCANNINg

the tX3340 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 tX3340 features two scan groups by default - open scan and
Group scan.
Open Scan
Allows any of the installed channels to be scanned for activity. if a
busy channel is found, scanning will pause to allow the signal to
be heard. once the channel has been clear for 5 seconds, scanning
will resume automatically.

e.g. scanning channels 1-8 in open scan.
Group Scan
Also allows any of the installed channels to be scanned for activity,
but in addition, it inserts your Priority channel into the scan
sequence. this means that your Priority channel will be monitored
regularly while scanning to ensure that no calls are missed. Any
signals received on your Priority channel will take precedence over
any signals received on the other channels.
