PRE-INSTALLATION SYSTEM TEST

1. The sensor and receiver are pre-matched (programmed) at the

factory. Test the system by flipping the sensor over while it is a
few feet away from the receiver. The receiver will show a
green light for closed when the sensor is face up in the vertical
position with the round end of the case pointing down
(Figure 1)

. The red light will flash when the sensor is face

down in the horizontal position (Figure 2).

2. If the green or the red receiver lights do not come on, or do

not react as described, see the Troubleshooting or Learning
section of these instructions.

NOTE: Because radio control devices are inherently susceptible
to RF interference, this product should NOT be used as a
stand-alone security device. This product is considered a
monitoring and notification device ONLY, and as such, should not
be used as a substitute for a dedicated home security system.

To ensure that your Garage Door Monitor continues to operate
properly, the following checks should be performed on a
monthly basis:
• Check that the sensor is mounted properly on the garage door

(see Mounting the Sensor section of this manual.)

• Ensure the 3 volt lithium battery is installed properly.
• Check to see that the receiver system is plugged into a wall

outlet and the jack is properly connected to the back of the
receiver. Make sure the antenna is straight and not in contact
with any metal objects.

• Check that the receiver is properly recognizing sensor

signals (see Troubleshooting section of this manual.)
