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

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

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 normal 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, 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.

HOW TO SEND A 2-TONE CODE

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

specific channel.
