CONVENTIONAL FEATURES
Busy Indicator
If the group is not automatically monitored as just described, it must be monitored manually. The simplest way to do this may be to note if a busy condition is indicated by the front panel multi-function indicator (see page 11). With scanning disabled and the squelch control properly adjusted (see page 18), note if this indicator is lighted green. If it is, a signal is being detected on the selected group (channel) and you should not transmit a message until it turns off.
Monitor Mode
There may be times when the Busy indication is displayed even though no one is using the channel. Monitoring should then be performed using the monitor mode. This mode is enabled by taking
the microphone off-hook, and is indicated by in the display as shown in the following illustration. The monitor mode temporarily disables Call Guard squelch (see page 47) and other squelch control techniques and also scanning so that all messages on the group are heard.
Monitor Mode
Selected
The transceiver may be programmed so that the microphone off-hook condition is not detected. The monitor mode is then not enabled when the microphone is taken off-hook. The Transmit Disable feature then may be used on all conventional groups so that manual monitoring is not required.
Monitoring may also be selectively disabled on each group by programming. Taking the microphone off-hook then does not enable monitoring on that group and monitoring is always performed by the Transmit Disable On Busy feature.
