•Protect the power cord. Power supply cords should be routed so that they won’t be walked on or
pinched by objects placed on or against them. Pay particular attention to cords at plugs, conve-
nience receptacles, and the point where they exit from the unit.
• Unplug the product from the wall outlet and disconnect the antenna or cable system during 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.
•Avoid overhead power lines. 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. When installing an outside antenna system, be extremely careful to keep from
touching the power lines or circuits. Contact with such lines can be fatal.
• Do not overload the wall outlet or extension cords. Overloading can result in fire or electric
shock.
• Do not insert anything through the openings in the unit, where they can touch dangerous voltage
points or damage parts. Never spill liquid of any kind on the product.
•Ground outdoor antennas. If an outside antenna is con-
nected to the product, be sure the antenna is grounded so
as to provide some protection against voltage surges and
built-up static charges. Section 810 of the National Elec-
trical Code, ANSI/NFPA No.70-1984, provides informa-
tion about 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
antenna discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode.
• Do not attempt to service the product 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 unit
- if the product has been exposed to rain or water
- if the product does not operate normally by following the operating instructions
- if the product has been dropped or the cabinet has been damaged
- when the product exhibits a distinct change in performance
• If you make adjustments yourself, adjust only those controls that are covered by the operating
instructions. Adjusting other controls may result in damage and will often require extensive work
by a qualified technician to restore the product 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 product, ask the service technician to
perform safety checks to determine that the product is in a safe operating condition.
