12 Rino ® 110 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 110 is scanning and it receivesan incoming signal, the Rino 110 automatically decodesthe Squelch Code used by the incoming signal. The Rino110 then uses that Squelch Code when it transmits backto that unit.The Code field isblank when the unit isscanning or monitoringchannels.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 Codecombinations 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, allowingyou to hear all activity on channel. If you see a brokentransmission symbol ( ), there is activity on yourselected channel, but the incoming signal does not matchthe Squelch Code your unit is using.
