About This Manual
This manual includes information on two CD radio cassette-
corders, the CFD-20 and CFD-30. First, refer to the model
name indicated on the top and bottom panels and check
what your model is. Any differences in appearance or
operation of the two models are clearly indicated in the
text, for example, “For CFD-30 only.” However, note that the
illustrations used in this manual are those of the CFD-30.
Precautions
Notes on power sources
Operate the unit only 120 AC or 9 V DC.
For AC operation, use the supplied AC power cord; do not
use any other type.
For battery operation, use six size D (R20) batteries.
eWhen the internal batteries will not be used, remove them
to avoid damage caused by battery leakage and corrosion.
eUnpiug the unit from the wall outlet when it is not to be
used for an extended period of time.
Note on handling the unit
eAs the laser beam used in the CD player section is
harmful to the eyes, do not attempt to disassemble the
casing. Refer servicing to qualified personnel only.
elf the unit is brought directly from a cold to a warm
location, or is placed in a very damp room, moisture may
condense on the lens inside the CD player section. Should
this occur, the player will not operate properly. In this
case, remove the disc and wait about an hour for the
moisture to evaporate.
eAvoid exposure to temperature extremes, direct sunlight,
dust, or mechanical shock.
*jf the unit is left in a car parked in the sun, be sure to
choose a location in the car where the unit will not be
subject to the direct rays of the sun.
eShould any solid object or liquid fail into the unit, unplug
the unit, remove the batteries, and have the unit checked
by qualified personne! before operating it any further.
Be careful not to lift the handle while the telescopic
antenna is in a raised position.
eAfter long storage, set the unit in playback mode and
warm it up for a few minutes before inserting a cassette.
Do not place anything within 10 mm of the side of the
cabinet. The ventilation holes must be unobstructed for the
proper operation of the unit and to prolong the life of its
components.
Since a strong magnet is used for the speakers, keep
personal credit cards using magnetic coding or spring-
wound watches away from the unit to prevent possible
damage from the magnet.
Note on cassettes longer than 90 minutes
The use of those cassettes is not recommended except for
long continuous recording or playback.
If you have any question or problem concerning your unit
that is not covered in this manual, consult your nearest
Sony dealer.
