Busy Channel Lockout

Busy Channel Lockout is a privacy feature that prevents the radio from listening to or transmitting over conversations outside its talkgroup, keeping lines of communication clear. Whenever the radio is not allowed to talk, you will hear busy tone if you attempt to transmit. The radio will be allowed to transmit:

1.when the channel is clear

2.during the group's repeater hang time, until a carrier drop is seen

3.when receiving transmissions from your own group (Common PL/DPL code).

Whenever a channel is programmed for PL/DPL busy chan- nel lockout, pressing the Control button does not put the radio into the carrier squelch mode. This means that the radios with PL/DPL busy channel lockout programmed can- not monitor or listen to the other groups' transmissions. Fur- thermore, the volume set function is also disabled on any channel that is preprogrammed as a PL/DPL busy channel lockout channel.

On carrier squelch channels, Transmit Inhibit is available to prohibit transmissions when any carrier is present.
