4. Don't short between the LIVE side ground and ISOLATED

(NEUTRAL) side ground or EARTH side ground when
repairing.

Some model's power circuit is partly different in the GND. The
diff er enc e of th e GND is s ho wn b y th e LIV E : (") side GND , the
ISO LATE D(N EUTRAL) : (#) si de GND and EARTH : ($) side
GND. Do n't s h or t bet we en th e LIV E sid e GN D an d

If above note will not be kep t, a fuse or any parts will b e broken.

5. If any repair has been made to the chassis, it is recommended
