1 Safety Precaution

TOP PREVIOUS NEXT

(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.

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 screw heads, antenna, control shafts, handle brackets, etc. Equipment with antenna terminals

should read between 3MO and 5.2MO toall 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.

2 Before Repair and Adjustment

TOP PREVIOUS NEXT

Disconnect AC power, discharge Power Supply Capacitors C12 through a 10 O, 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 over current.

Current consumption at AC 120 V, 50 Hz and 60 Hz in NO SIGNAL mode should be 50~130 mA and 40~80 mA

respectively.

3 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. 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 finishthe 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.
