Installing the Receiver
Use the transmitter to check the range of the receiver
before permanently mounting it
.
Consider the following when mounting the receiver:
• Standard receiver cable length is 10 feet (receivers with a longer cable are available as special
order items;
call the GTO Sales Department
). NEVER splice receiver cable!
•
Run the cable through PVC conduit to protect it from damage.
• DO NOT run cable through metal conduit because the receiver signal range will be decreased.
• DO NOT run cable in conduit containing ac wiring.
• DO NOT mount receiver on a metal fence or post; doing so will decrease signal range.
• The receiver range can vary from 50 to 100 feet depending upon weather, topography, and
external interference.
• DO NOT mount upside down.

IMPORTANT:
For safety reasons the obstruction
setting or
Stall Force
on the Mighty Mule® control
board comes from the factory set at
MIN
(mini-
mum). In many gate installations this setting will
need to be adjusted to overcome the weight and
size of the gates.
TThe
Stall Force
potentiometer on the control
board operates like a volume control on a radio. It
controls the obstruction sensitivity (or the amount
of force the opener will apply to an obstruction)
before it automatically stops and reverses direction
for approximately two (2) seconds.
Use a small slotted screwdriver to turn the arrow in
the center of the potentiometer. Adjust the sensitiv-
ity from the MINIMUM position where the gate
operates without obstructing from its own weight
or the wind conditions in your area.
NOTE: You may need to increase the
stall force in cold weather due to increased
resistance from gate hinges.
