Binary Code Method
Changing the transmitter RF ID using binary code is a simple process. All that is
needed is the unit itself, knowledge of representing an alphanumeric hex digit as a
four-digit binary number, and the method for entering the representative binary code
into the transmitter. The table following these procedures provides the binary code
for each single alphanumeric digit.
To enter binary code into the transmitter, do the following:
NOTE:
Hold the transmitter carefully to prevent accidental button presses while
disconnecting and reconnecting the battery.
1. Disconnect the battery.
2. Press and hold (for about 5 seconds) any single-function button while
reconnecting the battery, (this places the unit into programming mode), then
release the button. This first button is seen as a binary 0.
3. Press and release any other single-function button. This second button is
seen as a binary 1.
4. Before doing anything else, use these two buttons to enter the full eight-
digit binary code representing the 2-digit hexadecimal number.
For example, an RF ID of 40 consists of a hexadecimal “4”, represented as 0100 in
binary code, and a hexadecimal “0”, represented as 0000 in binary code. To change
the RF ID to 40, you need to enter the eight-digit binary code 01000000. Use the first
button to enter the 0s, and the second button to enter the 1.

Windows.
