3.1 Understanding Frequencies and Codes
3.1.1 F
REQUENCIES
Your radio operates on group of frequencies (see the
Appendix
for a complete
listing). You access frequency or frequencies through radio channel(s). You can
operate on any of your radio’s frequencies, but each must be licensed through the
FCC (see page 3).
To understand the difference between frequencies and channels, think of
channels as pre-set buttons on your car stereo and the frequencies as the many
radio stations available. You can select and save different stations (frequencies) to
pre-set buttons (channels) for easy access.

ODES
Codes filter out static, noise, and unwanted chatter on radio channels (see the
Appendix
for a complete listing). When you operate on a frequency with a code
set, you block out most interference on the frequency. This allows you to
communicate with less interference than when operating without a code.
Remember, since radio frequencies can be monitored, codes will not make your
conversations private.
NOTE
For compatibility with radios that do not have codes, the radio can be
set to Code “Off” in the programming mode. See the following
instructions.
NOTE
To talk to others in your group, all radios must be set to the same
channel and code.
There are settings programmed into your radio for frequencies and codes. If it is
necessary to confirm settings or to change them for licensing purposes, the radio
will audibly guide you through a series of programming steps.
