instructions.
ENG - iv
8. Do not install near any heat sources such as
radiators, heat registers, stoves, or other
apparatus (including ampliers) that produce
heat.
9. Do not defeat the safety purpose of the
polarized or grounding-type plug.
A polarized plug has two blades with one
wider than the other. A grounding type plug
has two blades and a third grounding prong.
The wide blade or the third prong are
provided for your safety. If the provided plug

where they exit from the apparatus.
11. Only use attachments/accessories specied
by the manufacturer.
12. Use only with the cart, stand,
tripod, bracket, or table
specied by the manufacturer,
or sold with the apparatus.
When a cart is used, use caution when
moving the cart/apparatus combination to
avoid injury from tip-over.
13. Unplug this apparatus during lightning
storms or when unused for long periods of
time.
14. Refer all servicing to qualied service

damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does
not operate normally, or has been dropped.
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.
