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:
Rx Indicator
- With scanning disabled, note if the “Rx”indicator in the
display is indicated. If it is not, the channel is not being used and you
can transmit your call. If it is indicated, the channel may be busy and
you should not place your call (see next paragraph).
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 by disabling Call Guard squelch using the Normal/
Selective option switch as described on page 32 or the monitor mode
described next.
Monitor Mode
The monitor mode temporarily disables squelch control features
(such as Call Guard
®
squelch) so that all messages are heard on the
selected channel. It also overrides the Busy Channel Lockout feature (see
next section) and temporarily halts scanning.
To monitor the selected channel, select the monitor mode by briefly
pressing or pressing and holding the Monitor option switch (if available).
The receiver unsquelches and a rushing noise or voice is heard when the
monitor mode is enabled. To disable the monitor mode and return to
normal operation, release the Monitor switch or press it a second time.
If scanning is enabled, pressing and holding the Monitor option
switch monitors the current scanned channel instead of the selected
channel if applicable.
