require the semiconductor description (X32, IC9 9 MPEG

u-COM) and disassembly for repair in detail.

Attention !

To avoid firing or other accident, the repair (in clouding

replacement of fuse) of the switching power supply

P.C.B. (W02-2568-35) is prohibited.

In case of the repair (defective P.C.B.), please replace

the complete P.C.B. with new one.

CONTENTS / ACCESSORIES / CAUTIONS

Beware of condensation

When water vapor comes into contact with the surface of cold

material, water drops are produced. If condensation occurs, correct

operation may not be possible, or the unit may not function correct -

ly. This is not a malfunction, however, and the unit should be dried.

(To do this, turn the POWER switch ON and leave the unit for sev -

eral hours.)

Be especially careful in the following conditions:

●When the unit is brought from a cold place to a warm place,

and there is a large temperature difference.

●When a heater starts operating.

●When the unit is brought from an air-conditioned place to a

place of high temperature with high humidity.

●When there is a large difference between the internal tempera -

ture of the unit and the ambient temperature, or in conditions

where condensation occurs easily.

CAUTION: For continued safety, replace safety critical components only with manufacturer's

recommended parts (refer to parts list). indicates safety critical components. For continued

protection against risk of fire, replace only with same type and rating fuse(s). To reduce the risk of

electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are

acceptably insulated from the supply circuit) before the appliance is returned to the customer.

The DC voltage is an actual reading measured with a high impedance type voltmeter. The

measurement value may vary depending on the measuring instruments used or on the product. Refer

to the voltage during LD PLAY unless otherwise specified; The value shown in ( ) is the voltage

measured at the moment of STOP. The voltage followed by (CD) refers to the value during CD PLAY.
