PRECAUTIONS ON SCHEMATIC DIAGRAMS
z
Due to the improvement in performance, some part numbers shown in the circuit diagrams
may not agree with those indicated in the Parts List.
z
The parts numbers, values and rated voltage etc. in the Schematic Diagrams are for
reference only.
z
Since the circuit diagrams are standard ones, the circuits and circuit constants may be
subject to change for improvement without any notice.

PRECAUTIONS ON PARTS LIST
z
The parts identified by the
symbol are critical for safety. Whenever replacing these parts, be sure to
use specified ones to secure the safety.
z
The parts not indicated in this Parts List and those which are filled with lines --- in the Parts No.
columns will not be supplied.
z
P.W. BOARD Ass'y will not be supplied, but those which are filled with the Parts No. in the Parts No.
columns will be supplied.
z
When ordering chips, screws etc., place bulk orders (unit of tens) whenever possible to improve
shipping efficiency.
z
There are cases where the actual implemented parts in the sets and the service parts are different.
When ordering parts, make sure to refer to the Parts List.

PRECAUTIONS ON SERVICE
Certain parts of the power circuits and the GNDs differ according to the models. Care must be
taken for the following points as the differences are indicated separately in the LIVE GND ( ) and
the ISOLATED (NEUTRAL) GND ( ).
1.
Do not touch the LIVE GND, or do not touch the LIVE GND and the ISOLATED (NEUTRAL)
GND at the same time. It may cause an electric shock.
Before pulling out the chassis or other parts, make sure to pull out the power cord from the
wall outlet first.
2.
Do not short circuit between the LIVE GND and ISOLATED (NEUTRAL) GND, or never
measure the LIVE GND and ISOLATED (NEUTRAL) GND at the same time using measuring
instruments (oscilloscope, etc.). It may blow fuses or damage other parts.
