9.Ventilation-Slots and openings in the cabinet and the back or bottom are provided for ventilation and to ensure reliable operation of the unit and to protect it from overheating, and these openings must not be blocked or covered. The open- ings should never be blocked by placing the unit on a bed, sofa, rug, or other similar surface. This unit should never be placed near or over a radiator or heat register. This unit should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s instructions have been adhered to.

10.Power Sources-This unit should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, con- sult your appliance dealer or local power company. For the units intended to operate from battery power, or other sources, refer to the operating instructions.

11.Grounding or Polarization-This unit is equipped with a polarized alternating-current line plug(a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try revers- ing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.

12.Power-CordProtection-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 par- ticular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.

13.Outdoor Antenna grounding-If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded so as to provide some protec- tion against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA No. 70, 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.

14.Lightning-For added protection for this unit receiver dur- ing a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the unit due to lightning and power-line surges.

15.Power Lines-An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

16.Overloading-Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.

17.Object and Liquid Entry-Never push objects of any kind into this unit through openings as they may touch danger- ous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the unit.

18.Servicing-Do not attempt to service this unit yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

19.Damage Requiring Service-Unplug this unit from the wall outlet and refer servicing to qualified service personnel under the following conditions:

a.When the power-supply cord or plug is damaged or frayed.

b.If liquid has been spilled, or objects have fallen into the unit.

c.If the unit has been exposed to rain or water.

d.If the unit does not operate normally by following the oper- ating instructions. Adjust only those controls that are cov- ered by the operating instructions, as improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the unit to its normal operation.

e.If the unit has been dropped or damaged in any way.

f.When the unit exhibits a distinct change in performance, this indicates a need for service.

20.Replacement Parts-When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer that have the same character- istics as the original part. Unauthorized substitutions may
