CTCSS/DCS

Once a DCS or CTCSS code is selected, your radio will now be in "Silent" mode on that channel

and will remain muted in that channel unless a signal containing your selected CTCC/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.

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.
