Section 6Conventional Features
Conventional mode features are radio features unique or used only when operating in
conventional mode.
6.1 Monitoring Before Transmitting
With conventional operation, you may need to manually monitor the channel before
transmitting to make sure that it is not being used by someone else. If you were to transmit
while someone else was using the channel, you would probably disrupt their conversation.
With SMARTNET/SmartZone and P25 Trunked operation, monitoring is performed
automatically. Monitor conventional channels automatically or manually as follows:
6.1.1 Automatic Channel Monitoring
If the selected channel is programmed for Busy Channel Lockout (also called Transmit
Disable On Busy), monitoring is performed automatically. Refer to Section 6.3 for more
information on this feature.
6.1.2 Manual Channel Monitoring
The automatic monitoring just described may occasionally disable the transmitter when
the channel is not in use, such as if the repeater has extended hang time. In this case, you
may not want to use it and the channel must then be monitored manually as follows:
