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

NOTE:
- Avoid using the sensor in places with large airflow and close to heat sources.
- Do not install the inductor directly in the sun or rain, or near metal.
- 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).
- The distance between the sensor and the receiver should be controlled at about 20 meters under the obstacle of the wall.
- If the doorbell has a short circuit or malfunction, check or replace the detector battery.
- If the ambient temperature is too high (more than 30 degrees), the sensing distance of the detector will be shortened. This is normal.

NOTE:
- Due to different lighting and screen settings, the colour of the item may differ slightly from the picture.
- Due to different manual measurement methods, please allow slightly different sizes.
