BUSY CHANNEL LOCK-OUT (BCL)
Busy Channel Lock-out function can be turned ON/OFF with program
software on every channel.
When activated, BCL prevents you from interfering with other parties
who may be using the same channel that you selected. Pressing the PTT
switch while the channel is in use
will cause your transceiver to emit an alert tone and transmission will be
inhibited (you cannot transmit). Release the PTT switch to stop the tone
and return to receive mode.
CTCSS/DCS
CTCSS (Continuous Tone Coded Squelch System)/ (Digital
Coded Squelch)
You may sometimes want to hear calls from only specific persons or
groups. In this case, use the selective call which allows
You to ignore unwanted calls from other persons who are using the same
frequency.
CTCSS or DCS is a sub-audible tone and is selectable from among the 39
or 83 tone frequency listed.
Note
CTCSS and DCS do not cause your conversation to be private and
scrambled. It only relieves you from listening to unwanted conversations.
