• Protect the power cord. Power supply cords should be routed so that they will not be walked
on or pinched by items placed on or against them. Pay particular attention to cord placement
at plugs, convenience receptacles, and at the point where they exit from the unit.
• Unplug the TV receiver from the wall outlet and disconnect the antenna or cable system dur-
ing a lightning storm or when left unattended and unused for long periods of time. This will
prevent damage to the unit due to lightning and power-line surges.
• An outside antenna system should not be placed 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.
Avoid overhead power lines: When installing an outside antenna system, be extremely careful
to keep from touching the power lines or circuits. Contact with such lines might be fatal.
• Do not overload the wall outlet or extension cords. Overloading can result in fire or electric
shock.
• Do not insert foreign objects through openings in the unit, as they may touch dangerous
voltages or cause damage. Never spill liquid of any kind on the TV receiver.
• Ground outdoor antennas. If an outside antenna or cable
system is connected to the TV receiver, be sure the
antenna or cable system is grounded so as to provide
some protection against voltage surges and built-up static
charges. Read 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.
• Do not attempt to service the TV receiver yourself. Refer all servicing to qualified service
personnel. Unplug the unit from the wall outlet and refer servicing to qualified service
personnel under the following conditions:
- When the power-supply cord or plug is damaged
- If liquid has been spilled on the unit or if objects have fallen into the TV
- If the TV receiver has been exposed to rain or water
- If the TV receiver does not operate normally by following the operating instructions
- If the TV receiver has been dropped or the cabinet has been damaged
- When the TV receiver exhibits a distinct degradation in performance
• If you make adjustments yourself, adjust only those controls that are covered by the operat-
ing instructions. Adjusting other controls may result in damage and will often require exten-
sive work by a qualified technician to restore the TV receiver to normal.
• When replacement parts are required, be sure the service technician uses replacement parts
specified by the manufacturer or those that have the same characteristics as the original part.
Unauthorized substitutions may result in additional damage to the unit.
• Upon completion of any service or repairs to this TV receiver, ask the service technician to
perform safety checks to determine that the TV receiver is in a safe operating condition.
