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.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

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 equilater

­al triangle is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.

“WARNING”

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

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.

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 power­sup ply cord or plug is dama ged, liqu id 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) Excessive sound pressure from earphones and
headphones can cause hearing loss.
