Program Frequency & Tone Codes
To match other radios, the owner can select Frequency, Tone and DQC Codes from Table 1, Table 2 and Table 3 .
In our example, we will program an LM-U450 to operate on the "Brown Dot" frequency of 464.500 MHz with 100.0
Hz tone.
1. Refer to Table 1 to determine the two-digit frequency code and write it down.
2. Refer to Table 2 to determine the two-digit tone code for 100.0 Hz and write it down.
3. Loosen the (4) captive screws in the front corners of the case. These screws are captive to
the housing; to prevent damaging them, DO NOT remove the screws from the housing.
4. Separate the case front from the case back, leaving the RPS-1A power supply or backup
battery connected to the radio.
NOTE: The voltage of the batteries must be greater than 6 VDC to program properly.
5. Press and HOLD the PROGRAM button. A "P" will appear on the program display as you
enter program mode and the radio will beep rapidly.
6. Release the PROGRAM button after the beeping has stopped. The radio will emit a triple
beep indicating that the radio is in program mode and a hyphen will appear on the program
display.
7. Scroll to the character “F” by clicking the PROGRAM button until the program display
shows the correct character. Pause —the radio will sound a low tone and show a hyphen
across the center of the display to indicate that it is ready to accept the first digit of the
frequency code.
8. Enter the 1
st
digit of the frequency code by clicking the PROGRAM button until the
program display shows the desired number. Pause —the radio will sound a low tone and
show a hyphen across the center of the display to indicate that it is ready to accept the
next digit.
9. Enter the 2
nd
digit of the frequency code by clicking the PROGRAM button until the
program display shows the desired number. Pause —the radio sounds a low tone and will
show a hyphen across the center of the display to indicate that it is ready to accept the
next digit.
10. Enter the 1
st
digit of the tone code (or 1
st
digit of the DQC code) by clicking the PROGRAM
button until the program display shows the desired number. Pause —the radio sounds a
low tone and will show a hyphen across the center of the display to indicate that it is ready
to accept the next digit.
11. Enter the 2
nd
digit of the tone code (or 2
nd
digit of the DQC code) by clicking the
PROGRAM button until the program display shows the desired number. Pause —the radio
sounds a low tone and will show a hyphen across the center of the display to indicate that
it is ready to accept the next digit.
12. FOR DQC CODES ONLY – Enter the 3
rd
digit of the DQC code by clicking the PROGRAM
button until the program display shows the desired number. Pause —the radio sounds a
low tone and will show a hyphen across the center of the display to indicate that it is ready
to accept the next digit.
13. Press and release the ENTER button to save your programming. A triple beep will sound to
indicate that programming was successful and a hyphen will appear on the program
display. The radio is now ready for another program entry.
NOTE: An error tone will sound if you attempt to save an incorrect code, an "E" will appear
on the display. Check the digits you are attempting to enter, then re-enter.
14. Once you have made your final program entry, press the ENTER button a final time to exit
programming mode. The Program display will be blank and the radio will be ready for use.
The Loudmouth
™

entries are attempted.
