Setting the Channel and Code
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.
NOTE: 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. Codes on are not a scrambling system!
Refer to the section on Voice Scramble operation.
Select from FRS 8–14, GMRS 1-7 & 15–22,
and 15R–22R GMRS repeater channels (with
Repeater Channels enabled).
