The menu of the entire system is divided into three parts: [Main Interface], [System Parameters] and [Advanced Parameters]. The main interface can set different scanning and laser-related parameters, and can display system status and alarm status information in real time; the system parameters can set system-related parameters, alarm parameters and authorization management. Advanced parameters can set higher-level restrictive parameters, and a password is required to enter the advanced parameters.

The main interface is divided into four areas: [Status Display Area 1], [Operation Status Area 2], [Parameter Area] and [Menu Area].

[Status Display Area 1]: Used to monitor whether the work lock signal, laser alarm and water chiller alarm are triggered. Normal processing can be carried out only when the display is green.

2. Lens Maintenance

To clean the cleaning head protective lens window, you need the following equipment:

(1) Powder-free rubber gloves or finger cots
(2) Lint-free optical fiber cleaning cloth and cotton swabs
(3) Anhydrous ethanol (optical grade, purity>99.5%)
(4) Light source (flashlight or mobile phone indicator light)
(5) Masking tape
(6) Microscope

Cleaning method: Spray isopropanol on a dust-free cleaning cotton swab. Hold the lens facing your eyes, gently pinch the side edge of the lens with your left thumb and index finger, hold the dust-free cleaning cotton swab with your right hand, and gently wipe both sides of the lens in a single direction from bottom to top or left to right (do not wipe back and forth to avoid secondary pollution of the lens). Then blow the lens surface with canned dry and pure compressed air to confirm that there is no foreign matter on the lens surface after cleaning.

Notes:

◎ Before using this product, check the cleanliness and damage degree of the protective lens. Using a dusty or damaged protective lens will damage the cleaning head (focusing lens, extension tube, etc.) and affect the effect.

◎ Private disassembly of the cleaning head and laser product will result in the loss of the warranty right of our company.

◎ Please clean the product in a dust-free environment with powder-free gloves or finger cots. Huanri Laser will not provide warranty for cleaning head damage caused by improper operation or incorrect cleaning procedures.

◎ The concentration of anhydrous ethanol used for cleaning must be greater than 99.5%.

3. Lens Disassembly and Assembly

The disassembly and assembly process must be completed in a clean place, and dust-free gloves or dust-free finger cots must be worn when disassembling and assembling the lens.

Disassembly and assembly steps:

Step 1: First clean all dust on the surface of the laser head.

Step 2: Rotate counterclockwise to take out the locking ring, then the protective lens can be replaced.
