Channels 1–14are for FRS, 15–22 are for GMRS channels (disabledby default in U.S. units), and 15R–22R are for GMRSrepeater 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/GMRSradios, provided the other radios use standard FRS/GMRS frequencies. A chart of Rino frequencies may befound in the “Appendix.”Squelch codes allow you to hear calls from only specificpersons. Thirty-eight (38) Squelch Codes (calledContinuous Tone Coded Squelch System or CTCSS)allow your Rino 130 to ignore unwanted calls from otherpersons using the same channel. Simply select the samesquelch code (number) as selected by the other person(s)with which you will communicate.Select from FRS 1–14, GMRS 15–22(with GMRS enabled), and 15R–22RGMRS repeater channels (with GMRSand Repeater Channels enabled).NOTE: Squelch codes do not cause your conversa-tion to be private. They only allow you to filter outother users on the same channel, so you only hearthe radios you want to hear. Squelch Codes are not ascrambling system!
