The lightning flash with arrowhead synbol within an
equilateral triangle is intended to alert the user to the
presence of uninsulated dangerous voltage within the
product's enclosure, that may be of s ufficient m agnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operation and maintenace (servicing) instruction in the
literature accompanying the appliance.

application.
Please read the basic protective measure as below before using:
1. Please read all the safety instruction before using the product.
2. This product must be earthed. If it should be malfunction or break
down, grounding provides a path of least resistance for electric
current to reduce risk of electric shock.
3. This product is equipped with a cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and earthed in accordance
with all local codes and ordinance.
Danger: Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check with a
qualified electrician or serviceman if you are in doubt as to
whether the product is properly grounded. Do not modify the
plug provided with the product - if it will not fit the outlet, have
a proper outlet installed by a qualified electrician.
4. To reduce the risk of injury, close supervision is necessary when
the product is used near children.
5. Do not use this product near water-for example, near a bathtub,
washbowl, kitchen sink, in wet basement or near a swimming pool
or the lake.
6. This product may be capable of producing sound levels that cloud
cause permanent hearing loss. Do not operate for a long period of
time at high volume level or at a level that is uncomfortable. If you
experience any hearing loss or ringing in the ears, you should consult
an audiologist.
7. This product should be located so that its location or position does
not interfere with its proper ventilation.
8. This product should be located away from heat sources such as
radiators, heat registers or other products that produce heat.
9. The product should be connected to a power supply only of the type
described on the operation instructions or as marked on the product.
10. This product may be equipped with a polarized line plug (one blade
wider than the other). This is a safety feature. If you are unable to
insert the plug into the outlet, contact an electrician to replace your
obsolete outlet. Do not defeat the safety purpose of the plug.
11. The power-supply cord of the product should be unplugged from
the outlet when left unused for a long period of time.
When unplugging the power-supply cord, do not pull on the cord,
but grasp it by the plug.
12. Care should be taken so that object do not fall and liquid are not
spilled into the enclosure through opening.
13. The product should be serviced by qualified service personnel when:
A. The power-supply cord or the plug has been damaged;
B. Objects have been fallen, or liquid has been spilled into the
product;
IMPORTANT SAFETY INS TRUCTIO N C. The product has been exposed to rain;
D. The product does not appear to operate normally or exhibits a
marked change in performance;
E. The product has been dropped or the enclosure damaged;
14. Do not attempt to service the product beyond that described in the
user-maintenance instructions. All other servicing should be
referred to qualified service personnel.
15. WARNING: Do not place objects on the product's power cord
or place it in a position where anyone could trip over, walk on
or roll anything over it. Do not allow the product to rest on or
to b e inst all ed over power cor ds of any typ e. Improper
installations of this type create the possibility of fire hazard
and/or personal injury.
16. The power-supply cord should be unplugged from the outlet when
the products is completely power off from the electric power sources
and electric networks .
