Scanning and Monitoring
The Scan option allows you to scan through the available
channels for voice activity. As the unit scans and
receives a signal (or if you transmit), it stops on that
channel/squelch code for a few seconds, then continues
scanning. When the Rino 130 is scanning and it receives
an incoming signal, the Rino 130 automatically decodes
the Squelch Code used by the incoming signal. The Rino
130 then uses that Squelch Code when it transmits back
to that unit.
You may use the Set Scanlist option to pick which
channels/squelch codes to scan. Scanning through the
all the channels can take time: Selecting only specific
channels/squelch codes decreases the scan time and
helps prevent the chances of missing a transmission.
The Scanlist also has Option Menu choices to
Scan Current Codes or Scan All Codes. Choosing Scan
Current Codes scans only the Channel and Squelch 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 automatically squelches a frequency
to filter out unwanted noise. Using the Monitor option
temporarily turns off the automatic squelch, allowing you
to hear the open channel. If you see a broken transmission
symbol (see page 18 ), there is activity on your selected
channel, but the incoming signal does not match the
Squelch Code your unit is using. You may choose to
monitor a channel if you wish to hear all the activity on a
channel.
To scan or monitor a channel(s):
1. Using the Thumb Stick, highlight the Scan or
Monitor button and then press the Thumb Stick
In. Scan starts searching through the available
channels. Monitor opens the channel to listen to
any radio transmissions on that channel.
2. To stop using either option, highlight the button
with the Thumb Stick and press In.
