Precautions
On safety
¢ As 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,
¢ Should any solid object or liquid fall into the player,
unplug the player, and have it checked by qualified
personnel before operating it any further.
On power sources
¢ For AC operation, use the supplied AC power cord; do
not use any other type.
¢ For battery operation, use six size D (R20) batteries.
¢ Unplug the player from the wall outlet when it is not to
be used for an extended period of time.
¢ When the batteries are not to be used for a long time,
remove them to avoid damage that can be caused by
battery leakage or corrosion.
¢ The nameplate indicating operating voltage, power
consumption, etc. is located at the rear,
On placement
¢ Do not leave the player in a location near heat sources, or
in a place subject to direct sunlight, excessive dust or
mechanical shock.
On operation
¢ If the player i 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 CD and wait about an hour for the
moisture to evaporate.
¢ If the player has not been used for a long time, set it in the
playback mode to warm it up for a few minutes before
inserting a CD or cassette.
Note on using a cassette with more than 90
minutes of play time
The use of a cassette with more than 90 minutes of play time
is not recommended except for long, continuous recording
or playback.
If you have any questions or problems concerning your
player, please consult your nearest Sony dealer.

Setting Up
Connecting the Speakers
For easy transport, the dual speakers are detachable. Before
you begin listening to music, attach the speaker boxes and
connect the speaker plugs as shown below. Make sure you
turn off the power before making any connections.
1 Align the grooves and slide the speaker box down until
it snaps into place. @
2 Connect the right speaker plug to the RIGHT
connectors and the left speaker plug to the LEFT
connectors.
To detach the speakers
Unlock the speaker @ and slide the speaker box all the way
up and away from the player.
4| Setting Up
Choosing Power Sources
The CD cassette-corder has two separate power sources.
Use the AC power source (house current) whenever you
record because recording consumes the most power. Use six
size D (R20) batteries when the CD cassette-corder becomes
a portable.
Operating the player on AC power
Insert one end of the supplied power cord to the AC IN
socket located at the rear of the player @ and the other end
to the wall outlet ©.
to wall outlet
Operating the player on batteries
To play your CD cassette-corder on batteries, the AC power
cord must be disconnected from the player. Unplug the
player and insert six size D (R20) batteries (not supplied)
in the compartment.
When to replace the batteries
Replace the batteries when the OPR/BATT indicator dims
or when the player stops operating.
When the batteries are weak, replace all the batteries with
new ones.

Adjusting the Sound Emphasis
When playing CDs, tapes, or radio programs, use the
ROTARY EQUALIZER controls to equalize the reproduced
sound and MEGA BASS to reinforce the bass sound. You
can also adjust the balance of the left and right output
levels.

Maintenance
Cleaning the lens
If the lens becomes dirty, it may cause a skipping of sound
during CD operation. Clean with a commercially available
blower.
Cleaning the tape heads and tape path
Contaminated heads cause poor recording or sound drop-
out in playback. We recommend cleaning after every 10
hours of operation. To make the best possible recording,
however, you should clean all surfaces over which tape
travels before each recording.
Wipe the heads, the pinch rollers and the capstans with a
cleaning swab slightly moistened with cleaning fluid or
alcohol.
Playback head Capstan
Pinch roller
Erase head Record/ Capstan
playback
head
Pinch roller
After cleaning the heads, rollers and the tape path, insert a
tape when the areas cleaned are completely dry.
Demagnetizing the tape heads
After 20 to 30 hours of use, enough residual magnetism
will have built up on the heads to begin to cause loss of
high frequency sound and hiss. At this time, you should
demagnetize the heads and all metal parts in the tape path
with a commercially available tape head demagnetizer.
Cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with a mild detergent solution. Do not
use any type of abrasive pad, scouring powder or solvent,
such as alcohol or benzene.
