1 Safety Precaution

(This “Safety Precaution” is applied only in U.S.A.)

1. Before servicing, unplug the power cord to prevent an electric shock.

2. When replacing parts, use only manufacturer’s recommended components for safety.

3. Check the condition of the power cord. Replace if wear or damage is evident.

4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.

5. Before returning the serviced equipment to the customer, be sure to make the following insulation resistance test to
prevent the customer from being exposed to a shock hazard.

1.1. Insulation Resistance Test

1. Unplug the power cord and short the two prongs of the plug with a jumper wire.

2. Turn on the power switch.

3. Measure the resistance value with ohmmeter between the jumper AC plug and each exposed metal cabinet part, such as
screwheads, antenna, control shafts, handle brackets, etc.
Equipment with antenna terminals should read between 3 MΩ and 5.2 MΩ to all exposed parts*.(Fig.1)
Equipment without antenna terminals should read approximately infinity to all exposed parts.(Fig.2)
*Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.

4. If the measurement is outside the specified limits, there is a possibility of a shock hazard. The equipment should be repaired
and rechecked before it is returned to the customer.

SA-DK10

2 Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C566~C569, C782 and C591 through a 10Ω, 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 120V, 60 Hz in NO SIGNAL mode should be ~650mA.

3 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.

5 Handling Precautions For Traverse Deck

SA-DK10

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).

5.1. Handling the Traverse Deck

(Optical pickup)

1. The traverse deck (optical pickup) is an extremely
highprecsion construction and must not be subjected to
impact, excessive vibration, or other types of rough
handling.

2. In order to prevent static electricity damage to the laser
diode, use a short pin or similar tool to short the optical
pickup’s flexible circuit boards after they have been
disconnected from the main circuit board.

3. Handle the flexible circuit boards with care; excessive force
could cause them to be broken.

4. Do not turn the pre-set variable resistor (for adjustment of
the laser power); it has been adjusted at the factory. (as
shown in Fig. 1)

5.2. 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 optical pickup is placed, and ground the sheet.
(sa shown in Fig. 2)

3.

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).

5.3. Caution when Replacing the
Traverse Deck

The traverse deck has a short point shorted with solder protect
the laer diode against electrostatics breakdown. Be sure to
remove the solder from the short point before making
connections.

SA-DK10

6 Precaution of Laser Diode

CAUTION:

This product utilizes a laser diode with th unit turned “ON”,
invisible laser radiation is emitted from the pick up lens.

CAUTION!

THIS PRODUCT UTILIZES A LASER.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT
IN HAZARDOUS RADIATION EXPOSURE.

1. Do not disassembly the pick up unit, since radioation from
exposed laser diode is dangerous.

2. Do not adjust the variable resistor on the pickup unit. It was
already adjusted.

3. Do not lock at the focus lens using optical instrument.

4. Recommend not to lock up lens for long time.
