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 battery cover of the sensor and the
back cover of the receiver. Note: Before opening the battery cover, it is
necessary to remove the transparent protective cover. Keep it for future
use. 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).
1. CODE CONNECTORS
Code Connectors on Receiver
After setting up all the connectors, both units are ready to be powered up.
Plug in the adapter to the receiver, the green LED will start flashing
indicating the receiver unit is powered up but no sensor is detected.
Push the detection rod to it’s fully retracted position. Re move the battery
cover on the sensor and insert the 3V lithium battery to the sensor as
shown in the diagram.
The LED on the sensor will flash 8 times to indicate the unit is properly
powered and there is signal transmission to the receiver. The green LED
on the receiver will stop flashing and stay on. Make sure to put the
transparent protective cover back in place after setting up.

mine the zone number 1, 2, 3, or 4.
These 2 connectors can be found by
opening the battery cover. Please

If the green LED on the receiver does not stop flashing, ensure the code
setting on the sensor is identical to the receiver. Position the sensor
vertically to allow the detection rod to drop. One of the LED on the
receiver will flash and the buzzer will also beep. Please put the battery
cover and transparent protective cover back in place.
You can install the sensor onto the garage door.
Note: The receiver may not be able to receive the signal from the
sensor properly if they are too close to each other. Move the sensor
further from the receiver to test again.
