SAFETY PRECAUTIONS
1. T he des ign of th is prod uct con ta ins sp ecial har dware, ma ny

p arts whic h have th ese sp ecial s afet y ch ar act erist ics ar e
ide ntified in the parts list of Ser vic e manua l. El ectric al
components having such features are ide ntified by shading
on the sche mat ic s and b y (!!!! ) on the parts list in Service
manual. The us e of a sub sti tu te r ep lac em en t which do es n ot

4. Don't shor t between the LIVE s ide ground and ISOLATED
(NE UTRAL) side ground or EARTH side ground when
repairing.
Some model's power circuit is partly different in the GND. T he
diff erenc e of th e GND is sh ow n by t he LIVE : (") side GN D, the
ISO LATE D(N EU TR AL) : ( #) side GN D an d EA RTH : ($) side
GND. Don't short between the LIVE side GND and
