Preparations
DV-705/DVF-R5070 (EN/K,P,E,Y)
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.
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.
