5. Observe original lead dress. Take extra care to
assure correct lead dress in the following areas:
a. near sharp edges, b. near thermally hot parts—
be sure that leads and components do not touch
thermally hot parts, c. the AC supply, d. high volt-
age, and e. antenna wiring. Always inspect in all
areas for pinched, out-of-place, or frayed wiring. Do
not change spacing between components, and be-
tween components and the printed-circuit board.
Check AC power cord for damage.
6. Components,parts, and/or wiring that appear to
have overheated or are otherwise damaged should
be replaced with components, parts, 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.
7. PRODUCT SAFETY NOTICE —Many
MultiSync
Monitor
electrical and mechanical parts have spe-
cial safety-related characteristics some of which
are often not evident from visual inspection, nor
can the protection they give necessarily be ob-
tained by replacing them with components rated
for higher voltage, wattage, etc. Parts that have
special safety characteristics are identified in this
service data by shading with a mark on schemat-
ics and by shading or a mark in the parts list. Use
of a substitute replacement part that does not have
the same safety characteristics as the recom-
mended replacement part in this service data parts
list might create shock, fire, and/or other hazards.
