Common troubleshooting

1, the light is off

Open the top cover, check whether the fuse is blown, and whether the power supply voltage is normal. If there is no problem with both, please find a professional to repair.

2, the transformer is damaged

Generally, there are two reasons for transformer damage. Power supply voltage problems and circuit short-circuits cause excessive current to cause transformer damage. The latter should be repaired by professionals.

3, the fuse is often damaged

Check whether the bulb in use is configured according to the rated power specified in the manual. A bulb with too large power will cause the capacity of the fuse to exceed the rated current and cause the fuse to be damaged. Check whether the power supply voltage is normal.

4, the disinfection handle is deformed

The handle of the shadowless lamp can be sterilized by high pressure (please refer to the instruction manual for details, but please note that the handle cannot be pressed against heavy objects during disinfection. The fragrance will cause the handle to deform.

5, the shadowless lamp rotates the angle, the lamp does not turn on

This is mainly because the sensors at both ends of the shadowless lamp boom will have poor contact after a period of use. In this case, you should ask a professional for maintenance.

6, shadowless light shift

In larger surgical shadowless lamps, after a period of use, due to the heavier weight of the inner lamp cap, greater friction is required for positioning, which will cause movement. It can be solved by tightening the upper positioning screw to increase the friction.

7, the brightness of the hole-type lamp becomes darker

The reflective glass bowl of the cold light hole shadowless lamp adopts coating technology. Generally, the domestic coating technology can only guarantee a two-year life. After two years, the coating layer will have problems, such as dark reflections and blistering. Therefore, it is necessary to replace the reflective bowl when encountering this situation.
