This document mainly introduces the precautions and warranty terms for semiconductor lasers. Users should pay attention to environmental conditions, voltage and current requirements, installation methods, and avoid eye damage. The warranty period is one year, but it does not cover customer disassembly, damage caused by contact with PC boards, damage to the outer surface, and expiration of the warranty period.
The manual lists safety precautions for operating the semiconductor laser, including environmental conditions, correct power connections, grounding, avoiding eye exposure, using protective eyewear, and handling the battery safely.
It also outlines the warranty terms, stating a one‑year warranty from the date of sale and conditions that void the warranty such as user disassembly or damage caused by improper use. This manual is written in Chinese.
Users must follow many safety rules: ensure proper environment, verify voltage and current, connect power correctly, ground the device, never point the beam at eyes or reflective surfaces, wear protective goggles, avoid use by children, and handle the battery safely.
The warranty lasts one year from the date of sale.
