In order for the sensor to communicate with the receiver properly, the
sensor’s code must match with the receiver’s code. Code connectors 1
to 6 can be found by opening the top cover of the sensor and the back
cover of the receiver. User is required to set these code connectors
randomly and the code settings on the sensor and receiver must be the
same. Each position of the code connector can be set to “+”, “-” or “0”
position. Refer to the diagram below to set the code connectors
properly. If the connector is placed on the top and middle posts, that
column is set on “ + ”. If the connector is placed on the middle and bottom
posts, that column is set on “ - ”. If the connector is removed completely,
(not placed on any posts), it is set to “ 0 ”. (see diagram for examples of
how to set a column to the three different positions).

If the sensor is face up in the vertical position, the
green LED on the receiver will glow steadily,
indicating the sensor is in a closed position.
If the sensor is face down in the horizontal
position, one of the red LED on the receiver will
flash, and the buzzer on the receiver unit will also
emit beeping to indicate a door is open.
You can change the orientation of the sensor and
you should see the change in response of the
receiver. If the sensor and receiver are working
properly in close proximity, you can now begin to
install the sensor onto your garage door.
NOTE: It is normal to hear a rattle from the
sensor when tilted or rotated to another position.

Attached the sensor to the garage door with double-sided foam tape if the
surface of your garage door is smooth and clean enough to provide a
good adhesive surface, such surface can usually be found on a metal
garage door. Please ensure the surface is smooth and clean.
For wooden garage doors, it is recommended to use the mounting plate
and screws as well.
Unplug the power cord of your garage door opener
