CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION:
TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
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 lightening 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.
“WARNING”
“TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOIS­TURE.”
SAFETY INSTRUCTIONS
Read instructions - All the safety and operating instruc-
1. tions should be read before the appliance is operated. Retain instructions - The safety and operating instructions
2. should be retained for future reference. Heed warnings - All warnings on the appliance and in the
3. operating instructions should be adhered to. Follow instructions - All operating and use instructions
4. should be followed. Water and Moisture - The appliance should not be used
5. near water - for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, and the like. Carts and Stands - The appliance should be used only
6. with a cart or stand that is recommended by the manufac­turer.
An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to over­turn. Wall or Ceiling Mounting - The appliance should be
7. mounted to a wall or ceiling only as recommended by the manufacturer. Ventilation - The appliance should be situated so that its
8. location or position does not interfere with its proper ven­tilation. For example, the appliance should not be situ­ated on a bed, sofa, rug, or similar surface that may block the 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.
ATTENTION:
POUR ÉVITER LES CHOCS ÉLECTRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRE­SPONDANTE DE LA PRISE ET POUSSER JUSQU' AU FOND.
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.
Heat - The appliance should be situated away from heat
9. sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat. Power Sources - The appliance should be connected to a
10. power supply only of the type described in the operating instructions or as marked on the appliance. Grounding or Polarization - The precautions that should
11. be taken so that the grounding or polarization means of an appliance is not defeated. Power Cord Protection - Power supply cords should be
12. routed 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, convenience recep­tacles, and the point where they exit from the appliance. Cleaning - The appliance should be cleaned only as rec-
13. ommended by the manufacturer. Nonuse Periods - The power cord of the appliance should
14. be unplugged from the outlet when left unused for a long period of time. Object and Liquid Entry - Care should be taken so that
15. objects do not fall and liquids are not spilled into the en­closure through openings. Damage requiring Service - The appliance should be ser-
16. viced by qualified service personnel when:
The power supply cord or the plug has been damaged;
A.
or Objects have fallen, or liquid has been spilled into the
B.
appliance; or The appliance has been exposed to rain; or
C.
The appliance does not appear to operate normally or
D.
exhibits a marked changed in performance; or The appliance has been dropped, or the enclosure
E.
damaged.
Servicing - The user should not attempt to service the ap-
17. pliance beyond that described in the operating instruc­tions. All other servicing should be referred to qualified service personnel.
