Adjusting The Volume And Squelch Level - Garmin 530 Owner's Manual

Setting the code to 0 (code off) allows 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
the "Appendix" for a table listing all of the 38 Codes and
their frequencies.
As you change channels, the Rino 520/530 remembers
the last channel/code combination that you were using.
For example, you may set the unit channel to 5 and code
to 21, then change the channel to 8 and code to 2. If you
change the channel back to 5, the code changes back to
its previous setting of 21. See the "Appendix" for more
information on FRS/GMRS and its operational aspects.
Choose from 38 codes. Setting
the unit to zero will allow you to
channel, but you must be on the
