RADIO PROGRAMMING
page 9
To match other radios, the owner can select Frequency and Tone Codes from Tables 1
and 2 on page 8.
In our example we will program channel 3 of a UHF radio to operate on the "Brown Dot"
frequency of 464.500 MHz (Frequency code "04") with 100.0 Hz tone (Tone code "12").
1. Refer to Table 1 on page 8 to determine the two digit frequency
code and write it down.
2. Refer to Table 2 on page 8 to determine the two digit tone code for
100.0 Hz and write it down.
3. Place the radio into Program/ Readout Mode by following the
instructions in FIG-6 on page 7. A " P " will appear on the LED
display as you enter program mode.
4. Using the Channel button and the LED display on the front of the
radio, select the channel number you wish to program.
5. When you have settled on a channel the display will show a
hyphen across the center to indicate that it is ready for
programming.
6. Using the PTT (push-to-talk) button and the LED display, select the
1 st digit of the 2-digit frequency code you wish to program into the
radio.
7. Pause—the display will change and show a hyphen, you will also
hear a short low tone.
8. Using the PTT (push-to-talk) button and the LED display, select the
2 nd digit of the 2-digit frequency code you wish to program into the
radio.
9. Pause—the display will change and show a hyphen, you will also
hear a short low tone.
10. Using the PTT (push-to-talk) button and the LED display, select the
1 st digit of the 2-digit tone code (or No Tone code "44") you wish to
program into the radio.
11. Pause—the display will change and show a hyphen, you will also
hear a short low tone.
12. Using the PTT (push-to-talk) button and the LED display, select the
2 nd digit of the 2-digit tone code (or No Tone code "44") you wish to

14. Press and release the On/ Volume Up to SAVE your programming
entry. The LED display will briefly show the channel number you
have just programmed and the radio will sound a triple beep to
indicate that programming was successful.
NOTE: An error tone will sound if you attempt to save an incorrect
code and an "E" will appear on the display. Turn the radio
OFF
,
check the digits you are attempting to enter, then start over.
15. To program another channel, repeat steps 4 through 14.
16. Turn the radio
OFF
and then
ON
again—the radio is now ready to
use.

a. YOU MUST enter "44" to enter "No Code" interference eliminator to match radios not
having tone codes. Refer to Table 2 on page 8.
