Purpose: In order to improve the quality of after-sales service, and provide feedback to customers at a low maintenance cost, the following service terms are specifically formulated.

Definition of Product Warranty Period: For products without a signed after-sales service agreement and not bound by sales contracts, the warranty period is calculated based on the date of manufacture indicated on the product nameplate.

• Hardware for the product is covered by a one-year warranty. Damage caused by impact leading to deformation or detachment of the entire machine, sensor damage, or internal component damage due to fiber optic leakage is not covered under the warranty period.
• Lens warranty coverage lasts for three months under the condition that the anti-tamper label is undamaged. If the anti-tamper label is damaged, the warranty period for collimating and focusing lenses involves compensation for replacement. Free replacement is provided for lens damage caused by inherent product quality issues, while damage caused by reasons other than inherent product quality issues requires chargeable repair or replacement during the warranty period and does not incur labor costs.
• Consumable parts such as protective lenses, nozzles, ceramic rings, and sealing rings are not covered under the warranty.
• Exclusions include product damage caused by failure to operate in accordance with the product operation manual requirements and damage resulting from human actions.
