Maintenance
Cleaning

- Wipe the frame with a damp cloth if necessary, avoiding direct contact with electronic components.
- Do not use abrasive cleaners or solvents.
Storage
When not in use, store the eyeglass loupe and its lenses in a clean, dry place, preferably in a protective case to prevent scratches and dust accumulation.
Battery Replacement
Replace the LR44 batteries when the LED lights dim or stop functioning. Refer to the "Battery Installation" section under Setup for instructions.
