Personal Transmitter Setting
All GTO transmitters have a standard setting and are ready to
operate your Mighty Mule Gate Opener. For your safety and
security, we strongly recommend that you replace the factory
setting with your own personal setting.
NOTE: If you have multiple transmitters, you should adjust all of
them at this time.
Step 1
Use a small phillips head screw driver to remove the transmitter
cover.
Step 2
Set the transmitter DIP switches using a small screwdriver.
There are nine (9) transmitter DIP switches; each can be
placed in three different positions (+, 0, –). DO NOT set all
the switches in the same position, such as all +, all 0, or all –.
Once the DIP switches have been reset, replace and close the
access cover.
WARNING: No other adjustments should be made inside the
transmitter.
Step 3
Program the new setting in the control board memory.
A. Slide the control box ON/OFF switch to the OFF position.
B. Press and hold the transmitter button while sliding the ON/
OFF switch to the ON position.
C. Continue to hold the transmitter button until the alarm
sounds (3-5 seconds).
D. Release the transmitter button. The new transmitter setting is now
programmed.
E. Verify that the transmitter operates the gate.
NOTE: It is NOT necessary to remove the cover of the control
box to program the new transmitter code, but when the control
box cover is removed the receiver range is reduced to less
than 5 feet.
