Maintenance
1. Cleaning
To clean the speaker, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used. Do not use harsh chemicals, cleaning solvents, or strong detergents, as these may damage the speaker's surface or internal components.

The BT-ZX0 speaker is IPX7 waterproof, meaning it can be submerged in water up to 1 meter (3 feet) for up to 30 minutes. Ensure the charging port cover is securely closed before exposing the speaker to water. After exposure to water, wipe the speaker dry before charging or opening the port cover.
