Conventional Mode Features
An overview of the conventional operating mode is located in Section 3.9.1. The
following information describes the features unique to analog and digital (Project 25)
conventional operation. Refer to the preceding “Radio Wide Features” (Section 4) for
information on features common to all operating modes.
5.1 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 transmit while
someone else is using the channel, you will disrupt their conversation. With SMARTNET/
SmartZone and P25 Trunked operation, monitoring is performed automatically. You can
monitor conventional channels automatically or manually.
5.1.1 Automatic Channel Monitoring
If the selected channel is programmed for Busy Channel Lockout (also called Transmit
Disable On Busy), monitoring is automatic. Refer to Section 5.3 for more information on
this feature.
