The Rino 120 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 FRS channels, 15–22 are GMRS channels (disabled 

by default in U.S. units), and 15R–22R are GMRS 

repeater channels (U.S. units only, 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 can be 

found in the “Appendix.”
Squelch codes allow you to hear calls from only specific 

persons. Thirty-eight (38) Squelch Codes (also called 

Continuous Tone Coded Squelch System or CTCSS) 

allow your Rino 120 to ignore unwanted calls from other 

persons using the same channel. Be sure everyone you 

will communicate with using your Rino has selected the 

same squelch code (number).
