Readout and Field Program 2-Tone, DTMF or Selcall Decode Operation
For special applications, it is desirable to program the Loudmouth
®
for 2-Tone, DTMF or Selcall decode operation. The user is able
to field program the radio for one of the 9 pre-determined 2-Tone pairs specified in
Table C
, or for any 3-7 digit DTMF or Selcall
sequence. The 2-Tone codes correspond to field programmable 2-Tone encode (transmit) codes available in other RITRON
products.
2-Tone, DTMF or Selcall decode can be used to selectively call the radio in a system where multiple radios operate on a single
frequency. When the radio is programmed for a 2-Tone, DTMF or Selcall Paging Decode code, no call will be heard unless the
code has been successfully decoded. After decoding, normal reception is possible without the need for the 2-tone, DTMF or Selcall
code. Paging Decode will be automatically reset after a programmable period of inactivity.
In the following example we will program for paging operation with 2-Tone Decode Code 94 frequencies of 389.0 and 669.9 Hz.
To enter a 2-Tone, DTMF or Selcall decode code:
1. Write down the desired 2-Tone, DTMF or Selcall ANI code.
2.
Place the radio into Program / Readout Mode
by pressing and holding the
PROGRAM
button. A “P” will
appear on the display. Release the
PROGRAM
button when a hyphen appears and the radio is ready to
accept the first digit of your program entry.
3. Click the
PROGRAM
button until the program display shows the Program Code “C”. Pause—the radio will
show a hyphen across the center of the display to indicate that it is ready to accept a 2-digit 2-Tone code, or
a 3 to 7-digit DTMF or Selcall decode sequence.
4.
TO REMOVE 2-TONE, DTMF OR SELCALL PROGRAMMING
– Enter a “0” using the
PROGRAM
button.
Pause
—the radio will show a hyphen across the center of the display to indicate that it is ready to accept the
next digit. Proceed to Step
10
to save this programming change.
5.
FOR DTMF CODES ONLY
– Enter a “1” using the
PROGRAM
button. Pause
—the radio will show a hyphen
across the center of the display to indicate that it is ready to accept the next digit.
6.
FOR SELCALL CODES ONLY
– Enter a “2” using the
PROGRAM
button. Pause
—the radio will show a
hyphen across the center of the display to indicate that it is ready to accept the next digit.
7. Enter the 1
st
digit of the 2-Tone code (or 1
st
digit of the DTMF or Selcall code) by clicking the
PROGRAM
button until the program display shows the desired number. Pause
—the radio will show a hyphen across the
center of the display to indicate that it is ready to accept the next digit.
8. Enter the 2
nd
digit of the 2-Tone code (or 2
nd
digit of the DTMF or Selcall code) by clicking the
PROGRAM
button until the program display shows the desired number. Pause
—the radio will show a hyphen across the
center of the display to indicate that it is ready to accept the next digit.
9.
FOR DTMF OR SELCALL CODES ONLY
– Enter the 3
rd
digit of the DTMF or Selcall decode sequence.
Pause
—the radio will show a hyphen across the center of the display to indicate that it is ready to accept the
next digit. Continue entering up to seven digits.
10. Press and release the
ENTER
button to save your programming. A hyphen will flash 3 times on the program
display to indicate that programming was successful. The radio is now ready for another program entry.
NOTE:
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.
11. Press the
PROGRAM
button to continue programming, or press the
ENTER
button to exit program mode.
To readout a 2-Tone, DTMF or Selcall decode programming:
1.
With the radio in program mode, click the
PROGRAM
button until the program display shows the Program Code
“C”. Pause—the radio will show a hyphen across the center of the display to indicate that it is ready to readout the
2-Tone, DTMF or Selcall programming.
2.
Press and release the
ENTER
button. The display will show a 2-digit 2-Tone code, a 1 followed by the 3 to 7-digit
DTMF code, or a 2 followed by 3 to 7-digit Selcall code. Each digit is separated by a hyphen.
2-TONE CODE
NOTE:
A zero (0) indicates that there is no 2-Tone, DTMF or Selcall decode programming.
3. Press the
PROGRAM
button to continue programming, or press the
ENTER
button to exit program mode.
