Setting the Channel and Squelch Code
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).
Select from FRS 1–14, GMRS 15–22 (with GMRS
enabled), and 15R–22R GMRS repeater channels
(with GMRS and Repeater Channels enabled;
available in U.S. units only).
NOTE: Squelch codes do not cause your conversa-
tion 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!
