which channels/codes to scan. Since it can take time to
scan through the all the channels, selecting only specifi c
channels/codes will decrease the scan time. Decreasing scan
time will help prevent the chances of missing a transmis-
sion. The Scanlist also has Option Menu choices to ‘Scan
Current Codes’ or ‘Scan All Codes’. Choosing ‘Scan Current
Codes’ will scan only the Channel and Code combination
in memory
The ‘Monitor’ option lets you listen to a single channel
for any activity, including static and weak voice signals.
The Rino series will automatically squelch a frequency to
lter out unwanted noise. Using the Monitor option will
temporarily turn off the automatic squelch allowing you
to hear the open channel. If you see a broken transmission
symbol (see pg. 9), you may be receiving a signal too weak
to trigger the unit’s squelch. You might choose this option
if a signal is getting out of range or weak.
