The Rino 520/530 has a total of 22 channels (not 

including GMRS repeater channels) and 38 codes to 

select from using the Channel and Code fields. Channels 

1–7 and 15-22 are GMRS channels, 8-14 are FRS 

channels, and 15R–22R are GMRS repeater channels 

(repeater channels are available on U.S. units only and 

are disabled by default). To communicate with other Rino 

and FRS/GMRS users, you must be on the same channel 

and 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)  Codes (called Continuous 

Tone Controlled Squelch System or CTCSS) allow 

your Rino 520/530 to ignore unwanted calls from other 

persons using the same channel. Simply select the same 

code (number) as selected by the other person(s) with 

which you plan to communicate.

Select from FRS 8–14, GMRS 1-7 & 15–22, 

and 15R–22R GMRS repeater channels (with  

Repeater Channels enabled).
