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

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 operationg condition.
Notes:
1. Item 3 is not required except for grounded or polarized equipment.
2. Item 17 and 18 are not required except for units provided with antenna terminals.
3. Item 17 complies with UL in the U.S.A.
