Setting the Channel and Squelch Code
The Rino 530 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 1–7
and 15-22 GMRS channels, 8-14 are FRS channels, and
15R–22R are for GMRS repeater channels (repeater
channels are available 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 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 may be found in the “Appendix.”
Squelch codes allow you to hear calls from only specific
Squelch codes allow you to hear calls from only specific
persons. Thirty-eight (38) Squelch Codes (called
Continuous Tone Coded Squelch System or CTCSS)
allow your Rino 530 to ignore unwanted calls from other
persons using the same channel. Simply select the same
squelch 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–22R
GMRS repeater channels (with GMRS
and Repeater Channels 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!
