Important Safety Instructions
Read these operating instructions carefully before
using the unit. Follow all the safety instructions
listed below. Keep these operating instructions
handy for future reference.
1. Read these instructions.
2. Keep these Instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Clean only with dry cloth.
6. Do not block any ventilation openings. Install
in accordance with the manufacturer’s
instructions.
7. Do not install near any heat sources such
as radiators, heat registers, stoves, or other
apparatus (including ampliers) that produce
heat.
8. Do not defeat the safety purpose of the
polarized or grounding-type plug. Apolarized
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 does not
t into your outlet, consult an electrician for
replacement of the obsolete outlet.
9. Protect the power cord from being walked on
or pinched particularly at plugs, convenience
receptacles, and the point where they exit
from the apparatus.
10. Only use attachments/accessories specied
by the manufacturer.
11. 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.
12. Unplug this apparatus during lightning
storms or when unused for long periods of
time.
13. Refer all servicing to qualied service
personnel. Servicing is required when
the apparatus has been damaged in any
way, such as power-supply cord or plug is
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 resistance
Check the following and use the unit correctly.
y
Deformation or damage from dropping the
unit or subjecting it to mechanical shock may
cause deterioration of the water resistance.
y
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.
y
Do not pour high-temperature water or blow
hot air from a hair dryer or any other appliance
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.
y
Handle the cap with care. Port cover and
AC plug cover play a very important role in
maintenance of the water resistance. 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 resistance may
deteriorate and may cause a malfunction of the
unit as a result of water entering the unit.
y
IPX4 cannot be met when any JACK or AC
power is plugged in.
y
Do not lay down the product horizontally to
ensure it remains water resistant.
