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 producing 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.

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.

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)

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.
