assure correct lead dress in the following areas:
a. near sharp edges, b. near thermally hot parts—

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.
