HOW TO FIELD PROGRAM TWO-TONE ENCODE CODES
THIS FEATURE AVAILABLE ON JMX-144D/446D/444D MODELS ONLY
For special applications, it is possible to use your Ritron portable radio or base station
for remote control applications; such as opening or closing a gate remotely (see Ritron
GateGuard at www.ritron.com/gg_04.pdf). This application requires you to program
your radio for 2-Tone encode operation.
The user can field program each channel with one of the 9 pre-set 2-Tone Codes
specified in Table 5. These codes correspond to field programmable 2-Tone Codes
available in the RITRON 6-Series OUTPOST Callbox. In our example we will program a UHF
radio to operate with 2-Tone Code #94.
Important Note:
You can ADD a 2-Tone Code to a channel if the Frequency Code and Tone Code
are not changed. Changing the Frequency Code or Tone Code of a channel will
ERASE any 2-Tone Code programmed on that channel. You must FIRST re-pro-
gram the channel to the desired Frequency Code and Tone Code and then SAVE
the entry by pressing the On/Volume Up button, then you may enter your 2-Tone
Code, remember you must also SAVE this entry by pressing the On/Volume Up
button.
1. Refer to Table 5 to determine the 2 digit, 2-Tone Code(s) you wish
to program into each specific channel.
2. Follow the instructions in Fig 6, page 7 to place the radio in the
Program/Readout Mode.
3. Using the channel button and the LED display on the radio, select
the channel number you want to program a 2-Tone Code into.
4. Enter the 1
st
digit of the 2-Tone code by clicking the PTT button
until the program display shows the desired number. Pausethe
radio will sound a low tone and show a hyphen across the
display to indicate that it is ready to accept the next digit.
5. Enter the 2
nd
digit of the 2-Tone code by clicking the PTT button
until the program display shows the desired number. Pausethe
radio sounds a low tone and will show a hyphen across the
display.
2-TONE CODE
If more than 5 digits are displayed during readout, the radio has been
programmed for 2-Tone Encode. The frequency and tone codes will be
displayed, followed by a C, then the radio will display the 2-Tone
code; see Table 5. In this example a UHF radio was programmed to
operate on the Brown Dot Frequency Code 04 (464.500 MHz) with
Tone Code 12 (100.0 Hz) and 2-Tone encode Code 94.
