How to care for the unit
Although the fabric part of the unit has water repellent treatment applied, you can use the unit more
comfortably and for a longer period of time by following the maintenance procedure below.
• If the surface of the unit gets dirty in the following cases, wash the unit with fresh water (tap water,
etc.) promptly to remove the dirt. Leaving dirt on its surface may cause the fabric part or the passive
radiator section (-) to discolor or deteriorate, or the unit to malfunction.
Ex.
– When salt, sand, etc. is stuck on the unit after using it on a beach, pool side, etc.
– When the unit is stained with sweat or foreign substances (sunscreen, suntan oil, etc.)
Note
• If the surface of the unit gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the
unit because it will affect the water repellent function of the fabric part of the unit.
• If sand grains, etc. enter the fabric or other part of the unit, remove them carefully. Never use a
vacuum cleaner, etc. on the unit. It may cause damage of the speaker section or other part of the unit.
