ENABLING CTCSS/DCS ON A CHANNEL
Once a CTCSS/DCS tone has been selected, it can be enabled on
individual channels.
1. Press the or keys to select the required channel.
2. Press and hold the
key. A high beep will be heard and
‘S’ will appear on the display. If a DCS tone is being used,
will also be displayed.
Your radio is now in ‘Silent’ mode and will remain muted on that
channel unless a signal containing your selected CTCSS/DCS tone
is received. Channels that do not have CTCSS/DCS enabled will
remain open to all signals.
You may activate CTCSS/DCS on as many channels as you wish
except channel 5 which is designated for emergency use.
NOTE: CTCSS/DCS may not work through some repeaters.
DISABLING CTCSS/DCS ON A CHANNEL
Repeat steps 1 and 2 above. A low beep will be heard and ‘S’
will disappear from the display.
NOTE: You will not be able to activate CTCSS/DCS on any
channel if the CTCSS/DCS tone is set to ‘OF’.
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
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
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.
