Scanning and Monitoring
The Scan option allows you to scan through the available
channels for activity. As the unit scans and detects
activity on a channel, it pauses on that channel/code for
a few seconds, then continues scanning. If you transmit
at that time you will be on that channel. When the Rino
520/530 is scanning and it receives an incoming signal,
the Rino 520/530 automatically decodes the Code used
by the incoming signal. The Rino 520/530 then uses that
Code when it transmits back to that unit. However, if you
transmit when the scan has not paused, the transmission
uses the channel set before scanning.
You may use the Set Scanlist option to pick which
channels/codes to scan. Scanning through all channels
can take time: Selecting only specific channels/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
Code combination in memory.
The Monitor option lets you listen to a single channel for
all activity, including static and weak signals. The Rino
requires the user to adjust the squelch for a frequency
to filter out unwanted noise. Using the Monitor option
temporarily turns off the squelch, allowing you to hear
the open channel. If you see an “Activity...” message,
there is activity on your selected channel, but the
incoming signal does not match the Code your unit is
using. You may choose to monitor a channel if you want
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.
