IMPORTANT SAFEGUARDS
Caution :
Read this page carefully to ensure safe operation.
13.Lightning
For added protection for this appliance 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 appliance due to lightning and power-line
surges.
14.Abnormal smell
– If an abnormal smell or smoke is
detected, immediately turn the power OFF and unplug
the appliance from the wall outlet. Contact your dealer or
nearest service center.
15.Damage requiring service
– The appliance should be
serviced by qualified service personnel when:
A.
The power-supply cord or the plug has been damaged.
B.
Objects have fallen, or liquid has been spilled into
the appliance.
C.
The appliance has been exposed to rain or water.
D.
The appliance does not appear to operate normally
by following the instruction manual. Adjust only those controls
that are covered by the instruction manual as an improper
adjustment of other controls may result in damage and will
often require extensive work by a qualified technician to
restore the appliance to its normal operation.
E.
The appliance has been dropped, or the enclosure
damaged.
F.
The appliance exhibits a marked change in performance.
16.Servicing
The user should not attempt to service the
appliance beyond that described in the instruction
manual. All other servicing should be referred to qualified
service personnel.
17.Outdoor antenna grounding
– If an outside antenna is
connected to the appliance, 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 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. See Figure.
18.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.
19.AC outlets
– Do not connect other audio equipment
with a power consumption larger than that specified to
the AC outlet on the rear panel.
Never connect other
electrical appliances, such as an iron or toaster, to it to
prevent fire or electric shock.
20. Overloading
– Do not overload wall outlets, extension cords,
or integral convenience receptacles as this can result in a risk
of fire or electric shock.
21. Attachment
– Do not use attachments not recommended by
the appliance manufacturer as they may cause hazards.
22. Replacement parts
– When replacement parts are required,
be sure the service technician has used replacement parts
specified by the manufacturer or have the same characteristics
as the original parts. Unauthorized substitutions may result in
fire, electric shock, or other hazards.
23. Safety check
– Upon completion of any service or repairs to
this appliance, ask the service technician to perform safety
checks to determine that the appliance is in proper operating
condition.
