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

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.

CAUTION: For continued safety,
replace safety critical components only
with manufacturer's recommended
parts (refer to parts list). indicates
safety critical components. For contin -
ued 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 insulat -
ed 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

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.

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.
