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
con will still appear on the display) but they 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

selected in the ‘RADIO SETTINGS’ menu. If CTCSS/DCS has been set to OFF, Silent
