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 and 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. When closing the cap, be
careful not to allow foreign objects inside. If
the cap is not closed completely the water
resistant may deteriorate and may cause a
malfunction of the unit as a result of water
entering the unit.
• IPX5 cannot be met when any JACK or AC
power is plugged in.
• The product cannot be dumped to ensure it is
water resistant.
