safety and operating instructions.

3. Adhere to all warnings and operating instructions.

4. Follow all operating and use instructions.

5. Warning: To reduce risk of fire or electrical shock,

do not expose this equipment to rain or moisture.

This unit is capable of producing high sound pres-

sure levels. Continued exposure to high sound pres-

sure levels can cause permanent hearing impair-

ment or loss. User caution is advised and ear protec-

tion is recommended when playing at high volumes.

6. Caution: to prevent electrical shock do not use this

(polarized) plug with an extension cord, receptacle

or other outlet unless the blades can be fully in-

serted to prevent blade exposure.

WARNING SHOCK HAZARD -

DO NOT OPEN.

The lightning flash with arrowhead, 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 sufficient magnitude to consti-
tute a risk of electric shock to persons

.

AVIS RISQUE DE CHOC -

NE PAS OUVRIR.

The exclamation point within an equilateral triangle is

intended to alert the user to the presence of important

operating and maintenance (servicing) instructions in

the literature accompanying the appliance.

NO USER-SERVICEABLE

PARTS INSIDE. REFER

SERVICING TO

QUALIFIED PERSONNEL

To prevent the risk of electric shock, do not remove

7. For added protection for this product during a lightning

storm, or when it is left unattended and unused for long

periods of time, unplug it from the wall outlet. This

will prevent damage to the product due to lightning or

power line surges.

8. Do not use attachments not recommended in this

owner’s manual as they may cause hazards.

Installation:

9. Locate the equipment for proper ventilation. For ex-

ample, the equipment should not be placed on a bed,

sofa, rug, or similar surface that may block ventilation

openings; or, placed in a built-in installation, such as a

bookcase or cabinet, that may impede the flow of air

through the ventilation openings.

10. Locate the equipment away from heat sources such as

radiators, heat registers, stoves, or other appliance (in-

cluding amplifiers) that produce heat.

11. Mount the equipment in a wall or cabinet only as de-

scribed in this owner’s manual.

12. Do not use this equipment near water; for example,

near a bathtub, washbowl, kitchen sink, laundry tub, in

a wet basement or near a swimming pool, etc.

13. Do not place this product on an unstable cart, stand,

tripod, bracket, or table. The equipment may fall, caus-

ing serious injury to a person, and serious damage to

the product.

Connection:

14. Connect this equipment only to the type of AC power

source as marked on the unit.

15. Route AC power cords so that they are not likely to be

walked on or pinched by items placed upon or against

them, paying particular attention to cords at plugs, con-

venience receptacles, and the point where they exit

from the instrument.

16. Do not defeat the inherent design features of the polar-

ized plug. Non-polarized line cord adapters will defeat

the safety provided by the polarized AC plug. If the

plug should fail to fit, contact your electrician to re-

place your obsolete outlet. Do not defeat the safety

purpose of the grounding-type plug.
