Sony SLV-D910AZ Service Manual page 6

6) 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 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 create shock, fire and/or other hazards. Product safety is
under review continuously and new instructions are issued
whenever appropriate.
