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.

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 (heat sinks, 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.
