1. Specifications are subject to change without notice. Weight and
dimensions are approximate.
2. Total harmonic distortion is measured by the digital spectrum analyzer.

1. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C536, C545, C546 through a 10 , 5W
resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid
state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
Current consumption at AC 230 V, 50 Hz in NO SIGNAL mode should be ~400mA.
2. Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
- No sound is heard when the power is turned on.
- Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative
speaker connection wires are
“shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the
amplifier are used.
If this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first turned off
and then on again.

4. Handling Precautions For Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference
caused by static electricity of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
- Handling of traverse deck (optical pickup)
1. Do not subject the traverse deck (optical pickup) to static electricity as
it is extremely sensitive to electrical shock.
2. The short land between the No.4(LD) and No.5(GND) pins on the
flexible board (FFC) is shorted with a solder build-up to prevent
damage to the laser diode.To connect to the PC board, be sure to open
by removing the solder build-up, and finish the work quickly.
3. Take care not to apply excessive stress to the flexible board (FFC).
4. Do not turn the variable resistor (laser power adjustment). It has
already been adjusted.

- Grounding for electrostatic breakdown prevention
1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity from
your body.
2. Work table grounding
Put a conductive material (sheet) or steel sheet on the area where the
traverse deck (optical pickup) is placed, and ground the sheet.
Caution :
The static electricity of your clothes will not be grounded through the
wrist strap. So, take care not to let your clothes touch the traverse
deck (optical pickup).
Caution when Replacing the Traverse Deck :
The traverse deck has a short point shorted with solder to protect the
laser diode against electrostatics breakdown. Be sure to remove the
solder from the short point before making connections.

5. Precaution of Laser Diode
Caution :
This product utilizes a laser diode with the unit turned "ON", invisible
laser radiation is emitted from the pick up lens. / Wavelength : 780 nm /
Maximum output radiation power from pick up : 100 W/VDE / Laser
radiation from pick up unit is safety level, but be sure the followings:
1. Do not disassemble the optical pick up unit, since radiation from
exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was already
adjusted.
3. Do not look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for a long time.
ACHTUNG :
Dieses Produkt enthält eine Laserdiode. Im eingeschalteten Zustand
wird unsichtbare Laserstrahlung von der Lasereinheit abgestrahlt. /
Wellenlänge : 780nm / Maximale Strahlungsleistung der Lasereinheit :
100 W/VDE / Die Strahlung an der Lasereinheit ist ungefährlich, wenn
folgende Punkte beachtet werden:
1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten
Laserdiode gefährlich ist.
2. Den werkseitig justierten Einstellregler der Lasereinhit nicht verstellen.
3. Nicht mit optischen Instrumenten in die Fokussierlinse blicken.
4. Nicht über längere Zeit in die Fokussierlinse blicken.
ADVARSEL: I dette a apparat anvendes laser.
