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.
9. Heat - The appliance should be situated away from heat sources such as radiators,
heat registers, stoves or other appliances (including amplifiers) that produce heat.
10. 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.
11. Grounding or Polarization - Precautions should be taken so that the grounding or
polarization means of an appliance is not defeated.
12. 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, paying
particular attention to cords at plugs, convenience receptacles and the point where
they exit from the appliance.
13. Protective Attachment Plug - The appliance is equipped with an attachment plug
having overload protection. This is a safety feature. See Instruction Manual for
replacement or resetting of protective device. If replacement of the plug is required,
be sure the service technician has used a replacement plug specified by the
manufacturer that has the same overload protection as the original plug.
14. Cleaning - The appliance should be cleaned only as recommended by the
manufacturer.
15. Power Lines - An outdoor antenna should be located away from power lines.
16. Outdoor Antenna Grounding - If an outside antenna is connected to the receiver, be
sure the antenna system is grounded so as to provide some protection against
voltage surges and built up static charges. Section 810 of the National Electrical
Code, ANSI/ NFPA No.70-1984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors, location of antenna discharge
unit, connection to grounding electrodes, and requirements for the grounding
electrode. See figure 1.
