CAUTION !Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.If Main Fuse (F1601) is blown , check to see that all components in the power supplycircuit are not defective before you connect the AC plug to the AC power supply.Otherwise it may cause some components in the power supply circuit to fail.

For continued protection against risk of fire, replace only with same type 4 A, 125V fuse.

CAUTION ! :

ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.4A 125V

NOTE:The voltage for parts in hot circuit is measured usinghot GND as a common terminal.

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTS

Standard Notes

WARNING

Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts that have these special safety characteristics are identified in this manual and its supplements; electrical components having such features are identified by the mark “#” in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts that do not have the same safety characteristics as specified in the parts list may create shock, fire, or other hazards.

Notes:1. Do not use the part number shown on these

drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since these drawings were prepared.

2. All resistance values are indicated in ohms (K = 103, M = 106).

3. Resistor wattages are 1/4W or 1/6W unless otherwise specified.

4. All capacitance values are indicated in µF (P = 10-6 µF).

5. All voltages are DC voltages unless otherwise specified.

1-11-2 X7TN_SC

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON THE FOLLOWING PAGES:

1. CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE_A,_V FUSE.ATTENTION: UTILISER UN FUSIBLE DE RECHANGE DE MÊME TYPE DE_A,_V.

2. CAUTION: Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.If Main Fuse (F1601) is blown, first check to see that all components in the power supply circuit are not defec-tive before you connect the AC plug to the AC power supply. Otherwise it may cause some components in thepower supply circuit to fail.

3. Note:1. Do not use the part number shown on the drawings for ordering. The correct part number is shown in the

parts list, and may be slightly different or amended since the drawings were prepared.

2. To maintain original function and reliability of repaired units, use only original replacement parts which are listed with their part numbers in the parts list section of the service manual.

4. Mode: SP/REC

Because a hot chassis ground is present in the powersupply circuit, an isolation transformer must be used.Also, in order to have the ability to increase the inputslowly,when troubleshooting this type power supplycircuit, a variable isolation transformer is required.



CAUTION ! :


CAUTION !Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.If Main Fuse (F1601) is blown , check to see that all components in the power supplycircuit are not defective before you connect the AC plug to the AC power supply.Otherwise it may cause some components in the power supply circuit to fail.
