18 MM462 Installation Instructions
Personalize Your 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. Make sure the control box is in the off position.
B. Press and hold the transmitter button while sliding the ON/OFF
switch to the ON position.
C. You will hear a series/pattern of beeps followed by a pause then a
single beep.
D. Release the transmitter's button and the beep will stop. Your
personnel code is now programmed.
E. This process may take 8 - 10 seconds.
Your other transmitters that have the same switch setting will now be
operational.
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.
