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.

INSTALLING THE BATTERY IN THE GARAGE

DOOR INDICATOR SENSOR

1. Place the screw driver blade on the tab at

the end of the case and gently press down

and in toward the case.

2. Insert the the lithium battery into the battery

clip with the + (positive) side face up.

3. Push the case back together tightly by

inserting the top hooks into the back cover,

then snap shut the bottom of

the case.

NOTE: It is normal to hear a rattle from the tilt switch in the sensor

when tilted or rotated to another position.

INDOOR RECEIVER SETUP

1. Plug the AC adapter into any

standard 110 volt AC electrical

wall outlet and the small plug

into the back of the indoor

receiver.

2. The receiver has a 9" antenna

wire which comes out the

back. The antenna should be

straight and not touching

metal.

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.)
