Rev. 11/03/09 • Printed in China for GTO, Inc.
How it works:
The Transmitter - Sensor:
The operating voltage for the transmitter is 3V from two alkaline ‘AA Size’ batteries (not included) inside
the transmitter. In cold weather lithium-alkaline batteries will perform best. There is no power switch for
this unit. Once the batteries are installed, the unit starts to function. IMPORTANT: Batteries should be installed
at the mounting location to ensure proper calibration of the sensor. You should install the batteries at the location by removing the
transmitter cover and then replacing it. The approximate transmitting range from the transmitter to the receiver is
400 ft. (at 433MHz). The range may vary depending on environmental conditions such as RF interference,
topography and construction of the building.
The Receiver:
The receiver is powered by an external power adaptor (AC120V 60Hz / DC 12V 100 mA). A rotary switch
controls the alert buzzer’s volume on the receiver. There are three LEDs on the front panel of the cabinet,
representing power (red), visitor alert (green) and low battery (red). A “RESET” button on the front panel is
used to clear the alert LED after it has registered passing vehicles.
Thank you for purchasing the Mighty Mule Driveway Alarm. Please read the directions carefully and
completely before installing.

Driveway Alarm
Place the SENSOR immediately next to the driveway to
maximize the sensing range, but at least 25 feet from
roadways, neighbor’s driveways or large moving metal
objects.
The 15 ft. cable connecting the SENSOR and
TRANSMITTER allows for the placement of the
TRANSMITTER away from the driveway in the concealment
of landscape or closer to the RECEIVER.
The approximate transmitting range from the
TRANSMITTER to the RECEIVER is 400 ft. Range can
vary depending on environmental conditions such as RF
interference and topography. Some adjustment may be
required.
NOTE: DO NOT place the TRANSMITTER in the
direct path of a sprinkler. The module is water
resistant but not waterproof.
