Important Safety Instructions

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in

accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radia-

tors, heat registers, stoves, or other apparatus
(including amplifiers) 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 pro-
vided for your safety. If the provided plug does not
fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

10. Protect the power cord from being walked on or

pinched particularly at plugs, convenience recepta-
cles, and the point where they exit from the appara-
tus.

11. Only use attachments/accessories specified by the

manufacturer.

12. Use only with the cart, stand,

tripod, bracket, or table spec-
ified by the manufacturer, or
sold with the apparatus.
When a cart is used, use cau-
tion 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 qualified 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.

15. Damage Requiring Service

Unplug the apparatus from the wall outlet and refer
servicing to qualified service personnel under the
following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen

into the apparatus,

C. If the apparatus has been exposed to rain or

water,

D. If the apparatus does not operate normally by

following the operating instructions. Adjust only
those controls that are covered by the operating
instructions as an improper adjustment of other
controls may result in damage and will often
require extensive work by a qualified technician
to restore the apparatus to its normal operation,

E. If the apparatus has been dropped or damaged in

any way, and

F. When the apparatus exhibits a distinct change in

performance this indicates a need for service.

16. Object and Liquid Entry

Never push objects of any kind into the apparatus
through openings as they may touch dangerous volt-
age points or short-out parts that could result in a
fire or electric shock.
The apparatus shall not be exposed to dripping or
splashing and no objects filled with liquids, such as
vases shall be placed on the apparatus.
Don’t put candles or other burning objects on top of
this unit.

17. Batteries

Always consider the environmental issues and fol-
low local regulations when disposing of batteries.

18. If you install the apparatus in a built-in installation,

such as a bookcase or rack, ensure that there is ade-
quate ventilation.
Leave 20 cm (8") of free space at the top and sides
and 10 cm (4") at the rear. The rear edge of the shelf
or board above the apparatus shall be set 10 cm (4")
away from the rear panel or wall, creating a flue-like
gap for warm air to escape.

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC 
SHOCK, DO NOT EXPOSE THIS APPARATUS 
TO RAIN OR MOISTURE.

CAUTION:

TO REDUCE THE RISK OF ELECTRIC SHOCK, 
DO NOT REMOVE COVER (OR BACK). NO 
USER-SERVICEABLE PARTS INSIDE. REFER 
SERVICING TO QUALIFIED SERVICE 
PERSONNEL.

The lightning flash with arrowhead symbol, 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 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 
operating and maintenance (servicing) instructions in 
the literature accompanying the appliance.
