1. The product is designed based on the principle of light-controlled induction, and can be used as a convenience store for visitors to report and business at night. The detection range is about 3-5 meters.
　
2. Working voltage DC: 1.5V (DC) battery model: AA R03P × 3 sections.
3. Ultra-low power consumption, standby current ≤ 0.1mA.
4. Each time the battery is installed, this product needs to carry out "self-inspection", about 10-15 seconds, and then enter the normal working state.
5. This product is recommended to be used under the condition of sufficient light. If the ambient light is insufficient, the detection distance will change from far to near.
Phenomenon, this is normal, when the music becomes weak, please replace the battery in time.
6. A variety of music can provide choices: A. Ding Dong, Hello! Welcome
B .Ding Dong,Hello,Welcome
C.Ding Dong,Salam Walaikum
