the indicated corrective action.
If the issue persists, contact your nearest Sony dealer.
If the STANDBY indicator ashes
Immediately unplug the power cord, and check the 
following item.
• If your system has a voltage selector, is the voltage 
selector set to the correct voltage?
Aer the STANDBY indicator stops ashing, 
reconnect the power cord, and turn on the system. If 
the issue persists, contact your nearest Sony dealer.

The sound exhibits excessive wow or utter or 
dropout.
• 
Clean the capstans and pinch rollers. Also, clean and 
demagnetize the tape heads. See “Precautions” for details.

Precautions
Discs that this system CAN play
• Audio CD
• CD-R/CD-RW (audio data/MP3 les)
Discs that this system CANNOT play
• CD-ROM
• CD-R/CD-RW other than those recorded in music CD 
format or MP3 format conforming to ISO9660 Level 
1/Level 2, Joliet or multisession
• CD-R/CD-RW recorded in multisession that have not 
ended by “closing the session”
• CD-R/CD-RW of poor recording quality, CD-R/CD-
RW that have scratches or are dirty, or CD-R/CD-RW 
recorded with an incompatible recording device
• CD-R/CD-RW which is nalized incorrectly
• Discs containing les other than MPEG 1 Audio Layer-
3 (MP3) les
• Discs of non-standard shape (for example, heart, 
square, star)
• Some discs that have adhesive tape, paper, or sticker 
attached to them
• Some rental or used discs with attached seals where the 
glue extends beyond the seal
• Some discs that have labels printed using ink that feels 
tacky when touched
Notes on discs
• Before playing, wipe the disc with a cleaning cloth from 
the center out to the edge.
• Do not clean discs with solvents, such as benzine 
thinner, or commercially available cleaners or anti-
static spray intended for vinyl LPs.
• Do not expose discs to direct sunlight or heat sources 
such as hot air ducts, nor leave it in a car parked in 
direct sunlight.
On safety
• e unit is not disconnected from the AC power source 
(mains) as long as it is connected to the wall socket, 
even if the unit itself has been turned o.
• Completely disconnect the power cord (mains lead) 
from the wall socket (mains) if it is not going to be used 
for an extended period of time. When unplugging the 
unit, always grip the plug. Never pull the cord itself.
• Should any solid object or liquid get into the system, 
unplug the system, and have it checked by qualied 
personnel before operating it again.
• e AC power cord can be changed only by a qualied 
service facility.
On placement
• Do not place the system in an inclined position or in 
locations that are extremely hot, cold, dusty, dirty, or 
humid or lacking adequate ventilation, or subject to 
vibration, direct sunlight or a bright light.
• Be careful when placing the unit or speakers on surfaces 
that have been specially treated (for example, with wax, 
oil, polish) as staining or discoloration of the surface 
may result.
• If the system 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, and 
cause the system to malfunction. In this situation, 
remove the disc, and leave the system turned on for 
about an hour until the moisture evaporates.
On heat buildup
• Heat buildup on the unit during operation is normal 
and is not cause for alarm.
• Do not touch the cabinet if it has been used 
continuously at a high volume because the cabinet may 
have become hot. 
• Do not obstruct the ventilation holes.
On the speaker system
is speaker system is not magnetically shielded, and 
the picture on nearby TV sets may become magnetically 
distorted. In this situation, turn o the TV, wait 15 to 30 
minutes, and turn it back on. 
If there is no improvement, move the speakers far away 
from the TV.
Cleaning the cabinet
Clean this system with a so cloth slightly moistened 
with a mild detergent solution. Do not use any type 
of abrasive pad, scouring powder, or solvent, such as 
thinner, benzine, or alcohol.
To prevent a tape from being accidentally 
recorded over
Break o the cassette’s overwrite protection tab from side 
A or B as illustrated.
Break o the 
cassette tab
To later reuse the tape for recording, cover the broken tab 
with adhesive tape.
About a tape longer than 90 minutes
e use of the tape with more than 90 minutes of play 
time is not recommended except for long, continuous 
recording or playback.
Cleaning the tape heads
Use dry- or wet-type cleaning cassette (available 
separately) aer every 10 hours of use, before you start an 
important recording, or aer playing an old tape. Failure 
to clean the tape heads can cause degraded sound quality 
or an inability of the unit to record or play tapes. For 
details, refer to the instructions of the cleaning cassette.
Demagnetizing the tape heads
Use a demagnetizing cassette (available separately) aer 
every 20 to 30 hours of use. Failure to demagnetize 
the tape heads can cause an increase in noise, a loss of 
high frequency sound, and an inability to completely 
erase tapes. For details, refer to the instructions of the 
demagnetizing cassette.
