No. CNICK Ring 3 is intended for general wellness and informational purposes only. It is not designed to diagnose, treat, cure, or prevent any disease or medical condition. Do not use its measurements as a substitute for professional medical advice, diagnosis, or treatment.
Remove the ring before:
• Working near exposed electrical components, vehicle batteries, engine bays, or energized equipment
• Operating machinery or power tools
• Lifting heavy weights
• Participating in activities where the ring could become caught, crushed, or struck
• Handling chemicals or abrasive materials
Metal rings can conduct electricity and may heat rapidly if they contact energized components. Rings can also create an entrapment or crushing risk during manual work. OSHA specifically identifies conductive rings and other jewelry as a potential hazard around exposed energized parts.
Remove it immediately only when it is safe to do so. Disconnect the charger if the ring is charging, move away from flammable materials, and do not use the product again.
Remove the ring immediately if it begins to change shape, feels unusually tight, becomes hot, or causes pain or restricted circulation. Seek medical assistance if the ring cannot be removed safely or if your finger is injured.
Do not wear, charge, or reuse a deformed ring. Contact CNICK Support and retain the ring for inspection.
Battery swelling is not normal and may indicate battery damage. Because the battery is sealed inside CNICK Ring 3, swelling may appear as a change in the ring’s shape, separation or cracking of the outer or inner surface, unusual heat, or other visible deformation.
If you notice any of these signs:
• Remove the ring immediately if it is safe to do so.
• Stop using and charging the ring.
• Do not squeeze, puncture, crush, bend, open, or attempt to repair it.
• Keep it away from heat, flames, water, and flammable materials.
• Contact CNICK Support for further instructions.
A swollen lithium-ion battery may create a fire or burn hazard. Do not dispose of the ring in household waste or ordinary recycling. Follow local requirements for disposing of damaged lithium-ion batteries or take the ring to an appropriate battery or hazardous-waste collection point.
CNICK Ring 3 is not a toy. Keep the ring, charging dock, cable, and packaging away from young children and pets. Children should use the product only under appropriate adult supervision.
