6. This schematic
diagram is the latest at the time of printing and subject to change without notice.
Note:
The
power
Circuit
board
contains
a
circuit area
which
uses
separate
power
supply
to isolate
the
ground
ccnnection.
The circuit is defined by HOT and COLD
indications
in
the
schematic
diagram.
Take
the following precautions.
PRECAUTIONS
1. Do not touch the hot
part
or the hot
and
cold parts
at
the same
lime,
or you
may
receive
a electric
shock.
2.
Do
not
short-circuit
the hot and cold circuits,
or
a fuse
may
blow
and
parts
may break.
3. Do
not connect
an instrument, such as an oscilloscope, to the hot and cold
circuits
simultaneously, or a fuse
may below. Connect the ground
of
instruments to the ground of
the
circuit
being
measured.
4. Make
sure
to
disconnect
the
power
plug before removing
the
chassis.
