IMPORTANT SAFEGUARDS
13.OUTDOOR ANTENNA GROUNDING - If an outside antenna or cable system is connected to the TV, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and
14.LIGHTNING - For added protection for this TV receiver during 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 TV 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 of 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 touch- ing such power lines or circuits as contact with them might be fatal.
16.OVERLOADING - Do not overload wall outlets and exten- sion 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 TV through openings as they may touch dangerous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the TV.
18.SERVICING - Do not attempt to service this TV yourself as opening or removing covers may expose you to dan- gerous voltage or other hazards. Refer all servicing to qualified service personnel.
19.DAMAGE REQUIRING SERVICE - Unplug this TV from the wall outlet and refer servicing to qualified service per- sonnel 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 TV.
c.If the TV has been exposed to rain or water.
d.If the TV does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions, as improper adjustment of other controls may result in damage and will often require extensive work by a qualified techni- cian to restore the TV to its normal operation.
e.If the TV has been dropped or damaged in any way.
f.When the TV 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 uses replacement parts specified by the manufacturer that have the same characteristics as the original part. Unauthorized substitu- tions may result in fire, electric shock, injury to persons or other hazards.
21.SAFETY CHECK - Upon completion of any service or repairs to this TV, ask the service technician to perform routine safety checks to determine that the TV is in proper operating condition.
22.HEAT - This TV product should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including amplifiers) that produce heat.
