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.

• The product cannot be dumped to ensure it is

water resistant.

• IPX5 cannot be met when any JACK is

plugged in.

• In a state of electricity, IPX5 can be met when

the power cord passes through the cover

power slot and the cover power is completely

closed, otherwise, it does not.
