SAFETY PRECAUTIONS
1. The design of this product contains special hardware and many
circuits and components specially for safety purposes. For
continued protection, no changes should be made to the original
design unless authorized in writing by the manufacturer.
Replacement parts must be identical to those used in the original
circuits. Service should be performed by qualified personnel
only.
2. Alterations of the design or circuitry of the product should not be
made. Any design alterations or additions will void the
manufacturer's warranty and will further relieve the manufacturer
of responsibility for personal injury or property damage resulting
therefrom.
3. Many electrical and mechanical parts in the product have special
safety-related characteristics. These characteristics are often not
evident from visual inspection nor can the protection afforded by
them necessary be obtained by using replacement components
rated for higher voltage, wattage, etc. Replacement parts which
have these special safety characteristics are identified in the
Parts List of Service Manual. Electrical components having such
features are identified by shading on the schematics and by (!)
on the Parts List in the Service Manual. The use of a substitute
replacement
which
does
not
have
the
same
safety
characteristics as the recommended replacement part shown in
the Parts List of Service Manual may cause shock, fire, or other
hazards.
4. The leads in the products are routed and dressed with ties,
clamps, tubing's, barriers and the like to be separated from live
parts, high temperature parts, moving parts and / or sharp edges
for the prevention of electric shock and fire hazard. When
service is required, the original lead routing and dress should be
observed, and it should be confirmed that they have been
returned to normal, after re-assembling.
WARNING
1. The equipment has been designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in accordance with the relevant safety standards.
4. It is essential that safety critical components are replaced by approved parts.
5. If mains voltage selector is provided, check setting for local voltage.
