12 Rino ® 130 Owner’s ManualU NIT OPERATION > R ADIO PAGEScanning and MonitoringThe Scan option allows you to scan through the availablechannels for voice activity. As the unit scans andreceives a signal (or if you transmit), it stops on thatchannel/squelch code for a few seconds, then continuesscanning. When the Rino 130 is scanning and it receivesan incoming signal, the Rino 130 automatically decodesthe Squelch Code used by the incoming signal. The Rino130 then uses that Squelch Code when it transmits backto that unit.You may use the Set Scanlist option to pick whichchannels/squelch codes to scan. Scanning through theall the channels can take time: Selecting only specificchannels/squelch codes decreases the scan time andhelps prevent the chances of missing a transmission.The Scanlist also has Option Menu choices toScan Current Codes or Scan All Codes. Choosing ScanCurrent Codes scans only the Channel and Squelch Codecombination in memory.The Monitor option lets you listen to a single channelfor any activity, including static and weak voice signals.The Rino series automatically squelches a frequencyto filter out unwanted noise. Using the Monitor optiontemporarily turns off the automatic squelch, allowing youto hear the open channel. If you see a broken transmissionsymbol (see page 18), there is activity on your selectedchannel, but the incoming signal does not match theSquelch Code your unit is using. You may choose tomonitor a channel if you wish to hear all the activity on achannel.To scan or monitor a channel(s):1. Using the Thumb Stick, highlight the Scan orMonitor button and then press the Thumb StickIn. Scan starts searching through the availablechannels.
