Frequency - The receive frequency of the selected channel is displayed
in megahertz.

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. Channels are
monitored automatically or manually as follows:
Automatic Channel Monitoring
If the selected channel is programmed for the Busy Channel Lockout
feature (consult your dealer), monitoring is performed automatically.
Refer to the description of this feature on page 26 for more information.
Manual Channel Monitoring
The automatic monitoring just described may not be programmed or
it may occasionally disable the transmitter even if the channel is not in
use. In this case, the channel must be monitored manually as follows:
Busy Indicator - With scanning disabled, note if the Transmit/Busy
indicator on the front panel is green. If it is not, the channel is not being
used and you can transmit your call. If it is on, the channel may be busy
and you should not place your call (see next paragraph).
