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.
