1. Kailun this alarm lock uses two gears. The first gear can only lock the car, but it does not alarm. The second gear can lock the car and has the alarm function.
2. Use the key to twist the lock cylinder and insert the second gear of the lock. When you hear a “beepâ€, the lock enters the alarm state. After 15 seconds, when the lock or the car is shaken, an alarm sounds. Continuous vibration continuous alarm, each alarm sound for 10 seconds.
3. When you hear a “squeaky, slightly, slightly,,,,,,†continuous sound or an alarm sound suddenly stops for less than 10 seconds, reminding the battery that it is exhausted, you need to replace the battery.
4. When replacing the battery, open the lock, unscrew the two screws next to the lock hole, and remove the rubber washer to replace the battery. Please pay attention to the positive and negative poles.
5. Important reminder: Please keep this manual for future battery replacement.
LED is the abbreviation of Light-Emitting Diode. It is made of semiconductor materials. It has a positive pole and a negative pole. When DC is applied to its positive and negative poles, it will emit light. From 1907 to 1993, LED has experienced 86 years of history. The application of LED technology is generally divided into visual and non-visual categories. The application of visual category includes LED lighting technology, and the non-visual category includes plant photosynthesis and medical care.
LED process:
The whole production process of LED Lamp Beads is divided into epitaxial chip production, chip production, and lamp bead packaging. The whole process reflects the manufacturing technology level of modern electronic industry. The manufacturing of LED is a combination of multiple technologies and a product with high technology content. The knowledge of LED for lighting purposes also needs to know how LED lamp beads are produced.
LED epitaxial wafer production process:
LED epitaxial wafer growth technology mainly uses organic metal chemical phase deposition (MOCVD) to produce synthetic materials with semiconductor characteristics, which is the raw material for manufacturing LED chips
