Readout Current Frequency, Tone and Selective Signaling Codes
1. 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.
2. 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.
3. Press and release the
PROGRAM
button (See
Loudmouth
™
receiver assembly
on page 2 for location). The
radio will immediately begin to display a series of digits; with each digit separated by a hyphen.
4. Write down the all the digits. The first two digits indicate the frequency code and the next two digits the tone
code;
see
Table 1
and
Table 2
on page 16.
In this example an LM-U450 is programmed to operate on the
“Brown Dot” frequency of 464.500 MHz (Frequency code “04”) with 100.0 Hz tone (Tone code “12”).
5. If a 5
th
digit is displayed, the Loudmouth
™
has been programmed for DQC and the last three digits indicate the
DQC code;
see
Table 3
on
page 16.
In this example an LM-U450 was programmed to operate on the “Brown
Dot” frequency of 464.500 MHz (Frequency code “04”) with a DQC code of “723”.
6. If more than 5 digits are displayed, the radio has been programmed for Selective Signaling Decode. The
frequency and tone codes will be displayed, followed by a “C”, then the radio will display either the 2-digit, 2-
Tone paging code (
see
Table 4
on 16
) or the 3-7 digit Selcall code
.
In this example an LM-U450 was
programmed to operate on the “Brown Dot” frequency of 464.500 MHz (Frequency code “04”) with 100.0 Hz
tone (Tone code “12”) and 2-tone paging decode frequencies of 330.5 Hz and 569.1 Hz (2-Tone code “91”)
7. If the Loudmouth
™
is PC programmed with any frequency not listed in
Table 1
on page 16, the radio will
display a code "99" for the frequency code. The PC programmer will be required to readout the radios
frequency programming.
8. Normal radio operation resumes after the programming information has been displayed.
