In major public transportation venues such as railway stations, airports and other places, security checks have become a common security facility. However Common problems and solutions, I hope it will be helpful to everyone.

Common problems and solutions of security checks:

1. Can't boot

① The indicator of the power supply is on, but whether the power supply in the inspection box is firmly inserted. If there is no problem, check whether the insurance pipe and part of the power supply are connected normally.

② The power supply indication is not bright. At this time, you need to test whether the laboratory is inserted firmly and whether the power cord is good.

2. Diversify objects, such as powder metal, linear metals, etc. It is not easy to detect

When installing, you must distinguish the left and right door panels, the left (4P plug), and the right (3P plug). If you want to insert firmly, you cannot reflect it, otherwise it is likely to cause problems. Check whether the strength of the inspection is often on when not alarm, and whether the infrared count is normal.

3. Do not call the police

① The strength and weakness are always bright. First, check whether there is a source of interference around, and then try to convert the crystal change frequency.

② Test whether infrared is normal.

4. Infrared

Check whether the infrared rays are firmly inserted and whether the infrared is covered.

5. The alarm time is long

Whether the setting of the alarm duration and the infrared count are normal.

6. LCD door flow phenomenon

Check whether the liquid crystal board is squeezed.
