Conventional Mode Features
An overview of the conventional operating mode is located in Section 3.11.1. The 
following information describes the features unique to analog and digital (Project 25) 
conventional operation.
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, "Busy Channel Lockout" 
for more information on this feature.
