UNIT OPERATION > RADIO PAGE
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.
