your Rino to ignore unwanted calls from other persons
who are using the same channel. Simply select the same
squelch code (number) as selected by the other person(s)
you desire to communicate with. NOTE: Squelch codes
do not cause your conversation to be private. They only
allow you to fi lter out other users on the same chan-
nel, so you only hear the radios you want to. Squelch
Codes are not a scrambling system! Setting the code to 0
(squelch code off) will allow you to hear all activity on the
selected channel, but you must be set to the same code
as the other person(s) to transmit back. See Appendix H
for a table listing all of the 38 Squelch Codes and their
frequencies.
As you change the main channels, the Rino will
remember the last channel/squelch code combination
that you were using. For example, you may set the unit
to Channel 5, squelch code 21, then change the main
channel to 8 and that code to 2. If you change the chan-
nel back to 5, the squelch code will change back to its
previous setting of 21.
See Appendix A for more information on FRS/GMRS
and its operational aspects.
To change the Channel and/or Code:
1. Using the CLICK STICK, highlight the ‘Channel’ or
‘Code’ field and then press the CLICK STICK key
IN. This will show a list of available channels/codes.
2. Move the CLICK STICK Up or Down to scroll
through the selections. Since not all the selections
can fit in the window, you will see a slider bar on
the right side indicating your current position in the
list.
3. Once you have highlighted the desired selection,
press IN on the CLICK STICK.
Scan and Monitor - Overview
The ‘Scan’ option allows you to scan through the
available channels for voice activity. As the unit scans and
receives a signal (or if you transmit), it will stop on that
channel/code for a few seconds, then continue scan-
ning. You may also use the Set Scanlist option to pick
Channels & Codes
/ Scan & Monitor
Choose from 38 squelch
codes. Setting the unit
to zero will allow you to
hear all transmissions
on that channel, but you
must be on the same code
to radio back.
The Code fi eld will go
blank when the unit is
scanning channels.
