1. During the operation, be careful and do not let hard objects touch the polished surface of the lens.
2. When cleaning the lens, first make sure that the detergent cannot corrode the lens coating.
3. When using the laser, when removing or covering the jumper head end cap, the jumper head port direction is inclined downward.
4. When the laser is not used, the jumper head cap provided by the manufacturer must be worn.
5. Generally, when there is grease on the lens and other stains that are difficult to clean, the immersion cleaning method is required. We need to ask professional after-sales technicians to clean here. It is not recommended to remove the protective lens directly for cleaning.
