2. Do not use optical instruments to look at the pickup lens.

Do not adjust the preset variable resistor on the optical pickup.

Do not disassemble the optical pickup unit.

If the optical pickup is replaced, use the manufactures specified replacement pickup only.

I Safety Precaution (This safety preoaution Is applied only in u.s.A.)

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

When replacing parts, use only manufactures recommended components for salely.

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

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

Betore 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.

@PWW.

O INSULATION RESISTANCE TEST

1. Unplug the power cord and short the two prongs oi the plug with a jump

2. Turn on the power switch.

3. Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such as
screwheads antenna, control shafts, handle brackets, etc. Equipment with antenna terminals should read between 3M9 and
5.2 M) to all exposed parts. (Fig. A) Equipment without antenna terminals should read approximately infinity to all exposed
parts. (Fig. B)

Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.

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