• After exposure to water, especially saltwater or chlorinated water, rinse the speaker with fresh water and allow it to air dry completely before charging or using the ports.
• Do not charge the speaker if the ports are wet.

If you encounter issues with your Monster S320 speaker, refer to the following common solutions:
