Setting the Channel and Squelch Code
The Rino 110 has a total of 22 channels and 38 squelch
codes to select from using the Channel and Code
fields. Channels 1–14 are FRS channels and 15–22 are
GMRS channels (disabled by default in U.S. units). 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 110 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 and GMRS
15–22 (with GMRS enabled)
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!
