Product operation instructions

1. Plug the receiver into the socket and power it on. Open the detector battery cover and install the battery.

2. Insert the rotating bracket into the back of the detector and clamp it

3. Push the detector switch to the ON position and wait for 10 seconds for the self check time before entering the normal working state

Precautions:

1. Try to avoid installing sensors directly facing high air flow and close to heat sources. (such as cold air vents, exhaust fan openings, electric furnaces, or nearby areas with heating, etc.). Do not install the sensor directly in areas exposed to sunlight and rain, and do not approach metal objects.

2. The sensor should be installed at a height of about 2 meters; The lateral detection of the sensor is more sensitive than that of a straight line (with the human body facing the sensor directly). It should generally be installed on the side or top of the entrance gate, and adjusted to a suitable position through the installation bracket to achieve the sensing effect

3. The distance between the sensor and receiver should be controlled at around 20 meters under the obstruction of a wall to minimize obstacles and interference from other wireless signals as much as possible.

4. If the doorbell experiences short reception distance or malfunction, please check the detector battery or replace it.
