To avoid deterioration of water resistant
Check the following and use the unit correctly.

• Deformation or damage from dropping the unit or subjecting it to mechanical shock may cause deterioration of the water resistant.
• This unit does not have a design that is resistant to water pressure. Use of the unit in a location where high water pressure is applied, such as in the shower, may cause a malfunction.
• Do not pour high-temperature water or blow hot air from a hair dryer or any other applicance on the unit directly. Also never use the unit in a place subject to high temperatures, such as in a sauna or near a heat source.
• Handle the cap with care. Port cover & AC plug cover plays a very important role in maintenance of the water resistant. When using the unit, make sure that the cap is closed completely.
