Avoiding Interference with Other Communications (Busy Channel Lockout (NXDN))

Busy Channel Lockout is the function to automatically restrict the transmission so as not to interfere with other
communications.
If an attempt is made to transmit on a channel that is already being used by other groups, the transceiver automatically
restricts the transmission.
If the PTT switch is pressed while Busy Channel Lockout is enabled, the transceiver cannot transmit with "BUSY"
appearing on the main display and a Warning Tone A sounding from the transceiver at the same time. The Warning Tone A
sounds from the transceiver until the PTT switch is released.
Following are conditions to disable transmission by Busy Channel Lockout (NXDN).
Configuration
Busy Channel Lockout is disabled. Transmission is not restricted even if the channel on which the
No
transceiver attempts to transmit is busy.
Carrier Only The transceiver cannot transmit while the transceiver is receiving a carrier.
The transceiver cannot transmit if the transceiver receives a carrier and the received RAN code does not
Incorrect RAN
match the RAN code preconfigured for the transceiver.
The transceiver cannot transmit if the transceiver receives a carrier and the received RAN code matches the
Correct RAN
RAN code preconfigured for the transceiver.
Any RAN The transceiver cannot transmit while receiving a RAN code.
The transceiver is controlled in the following manner according to the configuration for Transmit Mode on a channel where
"Mixed" is configured for Channel Type.
 If "Analog" is configured for Transmit Mode:
The transceiver transmits according to the configuration for Busy Channel Lockout (Analog).
 If "NXDN" is configured for Transmit Mode:
The transceiver transmits according to the configuration for Busy Channel Lockout (NXDN).
Also, while the Signaling Reset Timer or Auto Reset Timer is activated on a channel where "Mixed" is configured for
Channel Type, the transceiver transmits according to the configuration for Busy Channel Lockout in the same mode as
that of the received signal (Analog or NXDN). If the transceiver receives an analog signal, the transceiver will transmit
according to the configuration for Busy Channel Lockout (Analog). If the transceiver receives an NXDN signal, the
transceiver will transmit according to the configuration for Busy Channel Lockout (NXDN).
