Maintenance Instructions
| Cleaning steps | Operation method | Precautions |
|---|---|---|
| Dust removal | First use a blower/air bulb to blow off surface dust from the lens | Avoid wiping directly with a cloth to prevent scratching the coating |
| Wiping | Use a microfiber lens cloth, gently wipe clockwise from the center outward | If there are fingerprints/oil stains, apply a small amount of lens cleaning solution |
| Stubborn stains | Use professional lens cleaning wipes (e.g., Zeiss wipes) | Avoid using generic cleaners with unknown ingredients |
Important reminder: Clean the fish finder lens regularly. Keeping it clean ensures clear underwater images and prevents misjudgment caused by dirty lenses.
After use: After each removal from water, wipe the unit and lens dry with a soft cloth to avoid water residue.
Moisture-proof storage: When not in use for a long time, store in a dry cabinet with humidity controlled at 40%~50% to prevent lens fungus.
Avoid temperature differences: When moving from a cold environment to a warm indoor space, let the device acclimate to the temperature before powering on to prevent internal condensation.
