Setting the Channel and Squelch Code

The Rino 130 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 for FRS,
15–22 are for GMRS (disabled by default) 15R–22R are for GMRS repeater channels (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 persons. Thirty-eight (38) Squelch

Codes (called Continuous Tone Coded Squelch System or CTCSS) allow your Rino 130 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.

NOTE:

Squelch 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. Squelch Codes are not a scrambling system!

Setting the squelch code to 0 (squelch code off) allows you to hear all activity on the se-

lected channel, but you must be set to the same squelch code as the other person(s) to transmit
back. See the Appendix for a table listing all of the 38 Squelch Codes and their frequencies.

As you change the main channels, the Rino 130 remembers the last channel/squelch code

combination that you were using. For example, you may set the unit channel to 5 and squelch
code to 21, then change the main channel to 8 and squelch code to 2. If you change the chan-
nel back to 5, the squelch code changes back to its previous setting of 21. See the Appendix for
more information on FRS/GMRS and its operational aspects.
