1 Before Repair and Adjustment
TOP PREVIOUS NEXT
Disconnect AC power, discharge Power Supply Capacitors C301 through a 10 Ω, 5 W resistor to
ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver 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 220 V, 240 V, 60 Hz in NO SIGNAL mode should be ~100 mA
respectively.

2 Protection Circuitry
TOP PREVIOUS NEXT
The protection circuitry may have operated if either of the following conditions are noticed:
●No sound is heard when the power is turned on.
●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 ofthe 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
TOP PREVIOUS NEXT
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. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the
flexible board (FFC board).
3. Take care not to apply excessive stress to the flexible board (FFC board). When removing
or connecting the short pin, finish the job in as short time as possible.
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 place, 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).

file:///C|/Documents and Settings/eDOK/Рабочий стол/RX-ES22/s0400000000x.html
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
TOP PREVIOUS NEXT
Cross-Ref] 30611: Body: Caution:Caution:
This product utilizers a class 1 laser. Invisible laser radiation is emitted from the optical pick up lens.
When the unit is turned on:
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 enigeschalteten Zustand wird unsichtbare Laserstrahlung
von der Lasereinheit abgestrahlt.
Wellenlänge : 780nm
Maximale Strahlungsleistung der Lasereinheit : 100μW/VDE
DieStrahlung 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.
