Ventilation - The appliance should be situated so that its location or position does not interfere with its proper ven- ti

5、lation. For example, the appliance should not be situ- ated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, placed in a built-in installa- tion, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings. Heat - The appliance s

6、hould be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat. Power Sources - The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance

7、. Grounding or Polarization - The precautions that should be taken so that the grounding or polarization means of an appliance is not defeated. Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, pay

8、ing particular attention to cords at plugs, convenience recep- tacles, and the point where they exit from the appliance. Cleaning - The appliance should be cleaned only as rec- ommended by the manufacturer. Nonuse Periods - The power cord of the appliance should be unplugged from the outlet when lef

9、t unused for a long period of time. Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the en- closure through openings. Damage requiring Service - The appliance should be ser- viced by qualified service personnel when: A. B. C. D. E. Servicin

10、g - The user should not attempt to service the ap- pliance beyond that described in the operating instruc- tions. All other servicing should be referred to qualified service personnel.
