the old codes: press and hold the P1 button on the Control Board for ten seconds until
the red LED light begins to flash. (When the P1 button is released the red LED light will
turn off.)
2. Then press the P1 button one more time; the red LED will turn on and remain lit.
3. Next press and hold the T1 button on the remote transmitter until the red LED light blinks
once and the gates begin to open. Now the Control board is re-programmed to open
both gate wings (M1, M2) by pressing the T1 button.
Programming the T2 Button - Remote Control
This function, after being programmed, causes the T2 button on the remote will open one gate
wing (M1) only.
1. Using the T2 chart to the right, mark one
block either (On) or (Off) in all twelve
columns. This will be the new twelve-
button code sequence that is assigned
to the T2 button on the controllers.
2. Next press and hold both buttons (T1 & T2) until the LED stops flashing, turns off and
turns back on. Now the remote is in “Programming Mode”. Note: The remote will remain
in “Programming Mode” until a twelve button code sequence is entered; i.e. the twelve-
button code sequence from the chart above.
3. Press and hold the T2 button until the LED turns on. The T2 button is now ready to be
programmed. (If you release the button before the LED turns on, repeat this step.)
4. Next, press the first button in the T2 twelve-button code sequence from the chart above
(using T2 for ON and T1 for OFF). Be sure to hold down the button until the LED turns
on. Continue to enter the rest of the sequence in this manner until all twelve have been
entered. Once the twelve-button code has been entered successfully, the remote will
automatically return to its normal operating mode, indicated by the LED blinking while
either button is pressed.
NOTE: If you make a mistake while entering the coded sequence, continue entering the original
code until all twelve are entered, signified by the LED blinking while button is pressed.
Then repeat steps 2- 4 to restart the reprogramming process.
Programming the T2 Button - Control Panel
1. The codes were cleared in step 1 of Programming the T1 Button - Control Panel, do not

2. Press the P1 button on the control board (once) the red LED light will turn on and remain
lit.
3. Then press the P1 button again (once) the red LED light will blink and remain lit.
4. Next press and hold the T2 button on the remote transmitter until the red LED light blinks
once and one gate wing (M1) begins to open. Now the Control Board is programmed.
