Connect the receiver to 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 secure it 3. Push the detector switch to the ON position and wait for a self check time of 10 seconds before entering normal working mode Notes: 1. Sensors should be avoided as much as possible from being installed directly facing areas with high air flow and near heat sources. (such as: cold air outlet, exhaust fan outlet, electric stove or nearby areas with heating). Do not install the sensor directly in places exposed to sunlight and rain, and do not approach metal objects. 2.The sensor should be installed at a height of about 2 meters; Sensors are more sensitive to horizontal detection than straight lines (when the human body directly faces the sensor), and should generally be installed on the side or top of the entrance door. The sensor can be adjusted to a suitable position through a mounting bracket to achieve the sensing effect 3. Obstacles and interference from other wireless signals should be minimized as much as possible between the sensor and the receiver. Generally, under the obstruction of a wall, the distance between the sensor and the receiver should be controlled at around 20 meters 4. If the doorbell experiences short reception distance or malfunction, please check the detector battery or replace it. 5. If the ambient temperature exceeds 30 degrees Celsius, the sensing distance of the detector will be shortened, which is a normal phenomenon.
