2) Read and comply with all caution and safety re-
lated notes non or inside the cabinet, or on the chas-
sis.
3) Design Alteration Warning-Do not alter of add to
the mechanical or electrical design of this instru-
ment. Design alterations and additions, including
but not limited to, circuit modifications and the
addition of items such as auxiliary audio output
connections, might alter the safety characteristics of
this instrument and create a hazard to the user. Any
design alterations or additions will make you, the
service, responsible for personal injury or property
damage resulting therefrom.
4) Observe original lead dress. Take extra care to
assure correct lead dress in the following areas:
(1) near sharp edges, (2) near thermally hot parts (be
sure that leads and components do not touch ther-
mally hot parts), (3) the AC supply, (4) high voltage,
and (5) antenna wiring. Always inspect in all areas
for pinched, out-of-place, or frayed wiring, Do not
change spacing between a component and the
printed-circuit board. Check the AC power cord for
damage.
5) Components, parts, and/or wiring that appear to
have overheated or that are otherwise damaged
should be replaced with components, parts and/ or
wiring that meet original specifications.
Additionally, determine the cause of overheating
and/or damage and, if necessary, take corrective
action to remove any potential safety hazard.
6) Product Safety Notice-Some electrical and mechani-
cal 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 spe-
cial safety characteristics are identified by shading,
an ( )or a ( )on schematics and parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacement part might created shock, fire and/or
other hazards. Product safety is under review con-
tinuously and new instructions are issued whenev-
er appropriate.
