Additional Information Maintenance To clean the casing Use a soft cloth slightly moistened in water or a mild detergent solution. Do not use alcohol, benzine or thinner. To clean the headphones/ earphones plug Keep the plug of your headphones/earphones clean to obtain optimum sound. Wipe it with a dry, soft cloth. To remove any dust or sand from the rubber packing Any sand or dust on the rubber packing will prevent the lid from shutting tightly, and water may leak in. Brush off the dust once in a while.
