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 le ast resistance for e lec tri c
current to reduce risk of electric shock.
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.

DA NG ER - Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check with a
quali fied electr ician or serv iceman if you are in d oubt 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.

3. To reduce the risk of injury, close supervision is necessary when
the product is used near children.

4. Do not u se this product near wa ter-for examp le, nea r a ba thtub,
washbowl, kitchen sink, in wet basement or near a swimming pool
or the lake.

5. 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.

6. This product should be located so that its location or position does
not interfere with its proper ventilation.

7. This prod uct sho uld be located away from h eat sources such as
radiators, heat registers or other products that produce heat.

8. The product should be connected to a power supply only of the type
described on the operation instructions or as marked on the product.

9. 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.

10. 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.

11. Care should be taken so that object do not fall and liquid are not

spilled into the enclosure through opening.

12. The product should be serviced by qualified service personnel when:

A. The power-supply cord or the plug has been damaged; or
B. Objects have been fal len, or liquid has been spil led into the

product; or

C. The product has been exposed to rain; or
D. The product does not appear to operate normally or exhibits a
marked change in performance; or
E. The product has been dropped or the enclosure damaged..

13. 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.

14. WARN ING- Do not place objects on the product's power cord
