1.Safety Precautions
1.1 Pre-Use Inspection
Before use, inspect the helmet shell for cracks, deformation, or visible damage. Discontinue use immediately if any damage is found.
Check that the helmet lining and chin strap are intact, ensuring no loose or broken components.
Verify the battery level; ensure it is fully charged before operating.
Confirm that the SIM card and TF card are properly installed with no loose card holders.
1.2Precautions During Use
This product must be operated by trained professionals; minors are strictly prohibited from operating it.
Do not drill holes, graffiti, or modify the product arbitrarily, as this may compromise its protective performance and certification validity.
Do not store the product in high-temperature environments, open flames, highly corrosive liquids, or strong magnetic fields.
When using the explosion-proof version, strictly adhere to the explosion-proof operating procedures; do not use non-explosion-proof versions in areas with explosion hazards.
If the equipment exhibits abnormal heating, smoking, or unusual odors, immediately shut it down, move away from the hazardous area, and contact after-sales service promptly.
1.3 Maintenance and Care
Regularly wipe the housing and camera lens with a dry, soft cloth; avoid using organic solvents other than alcohol for cleaning.
The device has an IP66 protection rating; however, avoid direct immersion in liquids.
When not in use, store the device in a dry, well-ventilated area and keep it away from acids and alkalis.
It is recommended to perform a full charge-discharge cycle every 3-6 months; for extended periods of disuse, maintain the battery level at 40-60%.

All water-soluble coolants in this series are made from high-quality raw materials, combined with multifunctional additives such as rust and corrosion inhibitors, antioxidants, multi-functional emulsifiers, and specialty amines. They are carefully formulated into fully emulsified products, providing comprehensive protection for metalworking

Gear motors are used in a wide variety of applications, from industrial machinery to automotive systems to robotics. They are commonly used in situations where a high level of torque is required at low speeds, such as in conveyor systems or material handling equipment.

Zinc Oxide(ZnO) is white fine inorganic powder, odorless, insoluble in water, soluble in acid and strong alkali, with stable physical & chemical features, produced via indirect process, direct process and wet active process three mainstream production technologies to satisfy diversified global industrial standards.
Our full-series zinc oxide covers industrial, feed, food USP/FCC, all products are inspected strictly following international testing norms, low heavy metal residue enables global cross-region sales compliant with local chemical & food safety laws in all countries.
In rubber industry, it acts as core vulcanization activator and reinforcing filler for automobile tire, industrial rubber, latex products, greatly upgrade rubber elasticity, anti-oxidation and service lifespan, over 60% global ZnO consumption applied in rubber manufacturing field.
For paint, coating and ink industry, ZnO works as anti-rust, anti-UV, anti-mildew functional pigment, enhance coating weather resistance and surface gloss, reduce raw material cost by replacing partial titanium dioxide reasonably.
Ceramic & enamel field: excellent fluxing agent to decrease firing temperature, optimize glaze whiteness and gloss, widely used in construction ceramic, daily ceramic and art porcelain production.
Food, cosmetic grade ZnO meets FCC/USP/FDA standard: used as food zinc fortifier, skin ointment raw material and physical sunscreen core ingredient for cosmetics; nano ZnO owns superior UV blocking & antibacterial capacity for high-end skincare products.
Feed grade zinc oxide is legal animal nutrition additive globally, supplement essential zinc element for pig, poultry, aquatic livestock, improve digestion and disease resistance of breeding animals.
Besides, ZnO is also popular for plastic light stabilizer, textile anti-UV finishing agent, metal phosphating raw material and electronic varistor production, covering nearly all mainstream manufacturing industries across the world.
