SPIRIT M-SERIES 2-WAY RADIOS

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.

3.1.2 I

NTERFERENCE

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.

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.

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.
