Maintenance
Cleaning
Wipe the speaker with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure all port covers are securely closed before cleaning with moisture.

Water and Dust Resistance (IP68)
Image: The JUOVI ZS300 speaker partially submerged in shallow water, highlighting its IP68 waterproof rating. A note reminds users to keep rubber caps closed for water resistance.
The JUOVI ZS300 speaker is rated IP68, meaning it is fully dustproof and can withstand immersion in water up to 1.5 meters deep for 30 minutes. To maintain this rating, ensure all port covers are firmly sealed before exposing the speaker to water or dust. Do not expose the speaker to saltwater or other chemicals, as this may degrade its protective seals.
