1. After use, the power must be cut off.
2. When replacing the bulb, the 220V (or 110V) power switch installed on the wall must be turned off first, and the bulb can be replaced after it cools down.
3. Regularly check the connection status of each connection part of the shadowless lamp. Since the surgical shadowless light is a permanently suspended device, its safety is of paramount importance. The state of the connecting nuts and other connecting screws of the chassis of the rotating body must be checked regularly, and they should be tightened immediately if they are found to be loose.
4. The power transformer is placed in the wall or on the ceiling. The heat generated by the transformer in the control box cannot be dissipated, which may easily cause the transformer to burn out. Therefore, there should be enough space for heat dissipation around the transformer. It is easy to cause a large temperature difference, and there will be condensation on the ceiling or wall, which will cause the transformer to be entered with the water or be severely damped, and it is easy to cause a short circuit, so waterproof measures should also be taken.
