2 Rino ® 520/530 Owner’s ManualunItoperatIon>radIopageScanning.and.MonitoringThe Scan option allows you to scan through the availablechannels for activity. As the unit scans and detectsactivity on a channel, it pauses on that channel/code fora few seconds, then continues scanning. If you transmitat that time you will be on that channel. When the Rino520/530 is scanning and it receives an incoming signal,the Rino 520/530 automatically decodes the Code usedby the incoming signal. The Rino 520/530 then uses thatCode when it transmits back to that unit. However, if youtransmit when the scan has not paused, the transmissionuses the channel set before scanning.You may use the Set Scanlist option to pick whichchannels/codes to scan. Scanning through all channelscan take time: Selecting only specific channels/codesdecreases the scan time and helps prevent the chancesof missing a transmission. The Scanlist also has OptionMenu choices to Scan Current Codes or Scan All Codes.Choosing Scan Current Codes scans only the Channel andCode combination in memory.The Monitor option lets you listen to a single channel forall activity, including static and weak signals. The Rinorequires the user to adjust the squelch for a frequencyto filter out unwanted noise. Using the Monitor optiontemporarily turns off the squelch, allowing you to hearthe open channel. If you see an “Activity...” message,there is activity on your selected channel, but theincoming signal does not match the Code your unit isusing. You may choose to monitor a channel if you wantto hear all the activity on a channel.To.scan.or.monitor.a.channel(s):1.
