IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some electrical and mechanical parts have special
safety-related characteristics which are often not evident from visual inspection, nor can the protection
they give necessarily be obtained by replacing them
with components rated for higher voltage, wattage,
etc. Parts that have special safety characteristics are
identified by a ! on schematics and in parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might create shock, fire, and/or other
hazards. The Product’s Safety is under review continuously and new instructions are issued whenever
appropriate. Prior to shipment from the factory, our
products are carefully inspected to confirm with the
recognized product safety and electrical codes of the
countries in which they are to be sold. However, in
order to maintain such compliance, it is equally important to implement the following precautions when a set
is being serviced.
Precautions during Servicing
A. Parts identified by the ! symbol are critical for
safety. Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations
applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1)Wires covered with PVC tubing
2)Double insulated wires
3)High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1)Insulation tape
2)PVC tubing
3)Spacers
4)Insulators for transistors
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before soldering.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has been replaced, check that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
K. When connecting or disconnecting the internal
connectors, first, disconnect the AC plug from the
AC outlet.
1-3-1 DVD_SFNP
Safety Check after Servicing
Examine the area surrounding the repaired location
for damage or deterioration. Observe that screws,
parts, and wires have been returned to their original
positions. Afterwards, do the following tests and confirm the specified values to verify compliance with
safety standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)
Table 1 : Ratings for selected area
AC Line Voltage Clearance Distance (d), (d’)
220 to 240 V

Instructions for Handling Semiconductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by
electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1 MΩ) that is
properly grounded to remove any static electricity that
may be charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate
with proper grounding (1 MΩ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escape through the body grounding
band, be careful to avoid contacting semi-conductors
with your clothing.

HANDLING PRECAUTIONS FOR HDD
CAUTION:
1. SHOCK
a. Exposing HDD to shock may be the biggest
damaging factor. Please note that HDD is easily
damaged even if dropped from any height. Be sure
to place HDD on a shock-absorbent mat. Also, be
careful when transporting HDD.
b. Be careful not to subject HDD to any shock when
tightening screws for HDD replacement.
(Tighten screws manually, not with an electric
driver.)
2. MOISTURE
a. Moisture may also be a damaging factor. HDD is
semiclosed style. Sudden changes in ambient
temperature may cause moisture to form. Monitor
temperature and do not allow moisture to form on
the media surface. Also, when opening HDD
package, do so only after package is at ambient
temperature.
b. After replacing HDD, leave it to reach room
temperature (about 2 hours) for preventing dew
internal condensation, and then work necessary
task such as operation check.
4. OTHERS
a. Be careful so as not to do the followings.
Otherwise, HDD might be damaged.
- DO NOT disassemble HDD.
- When handling HDD, be sure to hold both sides
securely.
b. HDD should be stored, packed in the protective
bag, in suitable surroundings (i.e., no extreme
changes in temperature to avoid condensation).
c. When transporting HDD, be sure to use the
exclusive packing case (the replacement HDD
carton).
d. Do not stack HDDs.
e. Do not place vertically because HDD is unstable
and easy to fall.
3. STATIC ELECTRICITY
a. After removing HDD or taking replacement HDD
out of the protective bag (the replacement HDD is
packed in a protective bag), place HDD on a
conductive surface. A grounding band should be
worn when handling.
Grounding Band
Both the conductive surface and grounding band
should be grounded.
b. Make sure that HDD is placed on main unit
completely and then let go of it, when assembling.
c. Do not put HDD on a packing bag. (for preventing
electrostatic damage)
