1. Resistor
All the resistors are carbon 1/4W resistors, unless marked as follows.
The unit of resistance is an OHM [] (K=1 000 M=1 000000).
: Nonflammable : Metal Oxide
: Solid : Metal Film
: Wire Wound : Fuse

5. HOT and COLD indications
2. Interconnection Block Diagram DIA-7 The power circuit board contains a circuit area using a separate power supply to isolate the ground connection.
The circuit is defined by HOT and COLD indications in the schematic diagram. Take the precautions below:
3. Schematic Diagram DIA-8 6. This schematic diagram is the latest at the time of printing and the subject to change without notice.
3. 1. A -P.C.Board
3. 2. DG -P.C.Board Precautions
3. 3. DR -P.C.Board 1. NEVER touch the HOT part or the HOT and COLD parts at the same time, or you may get an electric shock.
3. 4. FM -P.C.Board 2. NEVER short-circuit the HOT and COLD circuits, or the fuse may blow and the parts may break.
3. 5. S / RM -P.C.Board 3. NEVER connect an instrument such oscilloscope to the HOT and COLD circuit simultaneously, or the fuse may blow.
3. 6. R / BR -P.C.Board Connect the ground of instruments to the ground of the circuit being measured.
3. 7. RT / RB -P.C.Board 4. MAKE SURE to unplug the power cord from the power outlet before removing the chassis.
3. 8. CW / M1 / M3 -P.C.Board 5. Be sure to make your orders of replacement parts according to parts list section.
