ance should be mounted to a wall or

ceiling only as recommended by the manufacturer.

5. Ventilation - The appliance should be situated so that its 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.

6. Heat - The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.

7. 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.

8. Grounding or Polarization - The precautions that should be taken so that the grounding or polarization means of an

appliance is not defeated.

9. 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.

10.Protective Attachment Plug - If 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.

11.Cleaning - The appliance should be cleaned only as recommended by the manufacturer.

12.Power Lines - An outdoor antenna should be located away from power lines.

1.SafetyPrecautions

13.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. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting

structure, grounding of the lead-in wire to an antenna-dis charge unit, size of grounding conductors,location of antennadischarge unit, connection to grounding electrodes and requirements for the grounding electrode. See Figure 1.

14.Non-use Periods - The power cord of the appliance should be unplugged from the outlet when left unused for a long period

of time.

15.Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.

16.Damage Requiring Service - The appliance should be serviced by qualified service personnel when:

a) The power-supply cord or the plug has been damaged; or b) Objects have fallen, or liquid has been spilled into the

appliance; or c) The appliance has been exposed to rain; or

d) The appliance does not appear to operate normally or exhibits a marked change in performance; or e) The appliance has been dropped, or the enclosure
