Caution : Read this page carefully to ensure safe operation.
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 dam-
aged.
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 exten-
sive work by a qualified technician to restore the ap-
pliance to its normal operation.
E. The appliance has been dropped, or the enclosure
damaged.
F. The appliance exhibits a marked change in perform-
ance.
16. Servicing – The user should not attempt to service the

manual. All other servicing should be referred to quali-
fied service personnel.
17. Outdoor antenna grounding – If an outside antenna is
connected to the appliance, be sure the antenna sys-
tem is grounded so as to provide some protection
against voltage surges and built up static charges. Arti-
cle 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 require-
ments 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 out-
side antenna system, extreme care should be taken to
keep from touching such power lines or circuits as con-
tact 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 recom-
mended by the appliance manufacturer as they may
cause hazards.
22. Replacement parts – When replacement parts are re-
quired, be sure the service technician has used replace-
ment 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 re-
pairs to this appliance, ask the service technician to per-
form safety checks to determine that the appliance is in
proper operating 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 pro-
vided with antenna terminals.
3. Item 17 complies with UL in the U.S.A.
