Setting the Channel and Squelch Code

The Rino 130 has a total of 22 channels (not including GMRS repeater channels) and 38 

squelch codes to select from using the ‘Channel’ and ‘Code’ fields.  Channels 1–14 are for FRS, 
15–22 are for GMRS (disabled by default) 15R–22R are for GMRS repeater channels (disabled 
by default).  To communicate with other Rino and FRS/GMRS users, you must be on the same 
channel and squelch code.  Garmin Rino units work with 3rd party FRS/GMRS radios, provided 
the other radios use standard FRS/GMRS frequencies.  A chart of Rino frequencies may be 
found in the Appendix.

Squelch codes allow you to hear calls from only specific persons.  Thirty-eight (38) Squelch 

Codes (called Continuous Tone Coded Squelch System or CTCSS) allow your Rino 130 to 
ignore unwanted calls from other persons using the same channel.  Simply select the same 
squelch code (number) as selected by the other person(s) with which you will communicate.  

Squelch codes do not cause your conversation to be private.  They only allow 

you to filter out other users on the same channel, so you only hear the radios you 
want to hear.  Squelch Codes are not a scrambling system!  

Setting the squelch code to 0 (squelch code off) allows you to hear all activity on the se-

lected channel, but you must be set to the same squelch code as the other person(s) to transmit 
back.  See the Appendix for a table listing all of the 38 Squelch Codes and their frequencies.  

As you change the main channels, the Rino 130 remembers the last channel/squelch code 

combination that you were using.  For example, you may set the unit channel to 5 and squelch 
code to 21, then change the main channel to 8 and squelch code to 2.  If you change the chan-
nel back to 5, the squelch code changes back to its previous setting of 21.  See the Appendix for 
more information on FRS/GMRS and its operational aspects.
