Product operation instructions
1. Plug the receiver into a socket to turn on the power, open the battery cover of the detector, and insert the battery
2. Place the rotating bracket on the back of the detector and get stuck
3. Push the detector switch to the ON position and wait for 10 seconds for the self-test. Enter normal working condition

Note:
1. Avoid using the sensor in places with large air flow and close to heat sources.
2. Do not install the inductor directly in the sun or rain, or near metal.
3. The sensor should be installed at a height of about 2 meters; the lateral sensor is more sensitive than a straight line (the human body directly faces the sensor).
4. The distance between the sensor and the receiver should be controlled at about 20 meters under the obstacle of the wall.
5. If the doorbell has a short circuit or malfunction, check or replace the detector battery.
6. If the ambient temperature is too high (more than 30 degrees), the sensing distance of the detector will be shortened. This is normal.
Due to different lighting and screen settings, the color of the item may differ slightly from the picture.
Due to different manual measurement methods, please allow slightly different sizes.
