HOW TO FIELD PROGRAM 2-TONE ENCODE CODES
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/pdf/gg_07.pdf ).
This application requires you to program the radio(s) that will be sending
the command for 2-Tone code operation, and radio(s) that will be
receiving the command (e.g. Ritron Callbox) for 2-Tone Encode
operation. The 2-Tone Codes must match.
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 or 7-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-program 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 7, page 12 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.
6. After you have entered the two digits, press and release the On /
Volume Up button to SAVE the entry. The LED display will briefly
show the channel number you have just programmed and then a
hyphen, the radio will sound a triple beep to indicate that
programming was successful.
An ERROR tone will sound if you attempt to save an incorrect code,
an “E” will appear on the LED display. Check the digits you are
attempting to program and start over.
7. You may program each channel with the same or a different 2-Tone
Code by repeating steps 3-6.
8. Turn the radio OFF and then ON again for no
rmal operation. The “Z”
button is used to send the 2-Tone Code. See HOW TO SEND A 2-
TONE CODE below.
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, fol
lowed 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.

HOW TO SEND A 2-TONE CODE

2.
Press the “Z” button to send the 2-Tone Code programmed for that
specific channel.
