Busy Channel Lockout; Bcl Override - Kenwood TK-3180 Function Reference

12 BUSY CHANNEL LOCKOUT

12.1 Busy Channel Lockout
This function automatically prevents a transmission so as
not to interfere other communications.
If a user transmits on a channel while other groups are
using that channel, the user may interfere with
communications. This function prevents such
interference.
The "BUSY" icon appears on the main display when the
PTT switch is pressed while this function is enabled. The
transceiver emits a Warning Tone and does not transmit.
The transceiver emits the Warning Tone until the PTT
switch is released.
You can configure the Busy Channel Lockout function for
each channel using the KPG-89D. The following table
shows the conditions to inhibit transmission with the Busy
Channel Lockout function.
