Product Operating Instructions

1. Plug the receiver into the power outlet, open the battery cover on the detector, and insert the battery.

2. Place the rotating bracket on the back of the detector and secure it.

3. Push the detector switch to the ON position, wait 10 seconds for the self-test, and then enter normal operating mode.

Precautions:

1. Try to avoid installing the sensor in a position directly facing a high airflow and near a heat source. (Such as: cold air vent, exhaust fan, electric furnace, or nearby heater, etc.). Do not install the sensor in direct sunlight or rain, or near metal objects.

2. The sensor should be installed at a height of approximately 2 meters. Horizontal detection is more sensitive than straight-line detection (when the human body is directly facing the sensor). Generally, it should be installed on the side or top of the front door, and the sensor should be adjusted to a suitable position using the mounting bracket to achieve induction. 3. Interference between the sensor and the receiver from obstacles and other wireless signals should be minimized as much as possible. Generally, when obstructed by a wall, the distance between the sensor and the receiver should be approximately 20 meters. 4. If the doorbell has a short reception range or malfunctions, please check or replace the detector's battery. 5. If the ambient temperature is too high (over 30 degrees), the detector's detection range will be reduced, which is normal. Packing list: 1 x receiver + 2 x transmitters
