On placement
Do not place the system in a n inclined position o r in
locations tha t are extr emely ho t, cold, dus ty , dir ty , o r
humid o r lacking adequat e ventila tion, or sub ject to
vibra tion, direct sunlight o r a bright light.
Be careful when placing the unit or s peakers on
surfaces that ha ve been specially treated (for exa mple ,
with wax, oil, polish) as sta ining or discolo ration o f the
surface may r esult.
If the syst em is bro ught dir ectly from a cold to a warm
location or is p laced in a very damp room, mo isture
may co ndense on the lens inside the CD p layer , and
cause the system to malfunction. I n this situa tion,
remo ve the disc, and leav e the system turned on f or
about a n hour un til the moistur e evapora tes.
On heat buildup
H eat buildu p on the uni t during opera tion is normal
and is no t cause for ala rm.
Do not to uch the cabinet if i t has been used
con tinuousl y at a high vo lume because the cabin et may
have becom e hot.
Do not obstruct the ventila tion holes.
On the speaker syst em
is speaker system is not ma gnetically shielded, and
the picture o n nearby TV sets may become magnetically
distorted. I n this situa tion, turn o the TV , wai t 15 to 30
minu tes, and turn i t back on.
If there is n o imp rov ement, m ove the speakers far a wa y
from the TV .
Cleaning the cabinet
Clean this system with a so cloth sligh tly mois tened
with a mild detergen t solutio n. Do not use an y type
of ab rasive pad, scouring pow der , or solvent, such as
thinner , benzine, o r alcohol.
T o prevent a tape fr om being accidentally
recorded o ver (Ex cept f or the UK model)
Break o the cassett e ’ s o verwrite prot ection tab from side
A or B as illustra ted.
Break o the cassette
tab
T o later r euse the tape for r ecording, co ver the br oken tab
with adhesive tape.
About a tape longer than 90 minutes (Exc ept
for the UK model)
e use of the tape with mo re than 90 min utes o f play
time is not reco mmended except f or lon g, contin uous
recor ding or pla yback.
Cleaning the tape heads (Exc ept for the UK
model)
U se dry- or wet-type cleaning cassette (a vailable
separatel y) aer every 10 hours of use, befo re yo u start an
importan t recor ding, or a er playing a n old tape. F ailur e
to clean the tape heads can ca use degraded sound quality
or an ina bility of the uni t to reco rd or pla y tapes. F or
details, refer to the in structions of the cleaning cas sette.
Demagnetizing the tape heads (Exc ept for the
UK model)
U se a demagnetizing cassett e (availab le separatel y) aer
every 20 to 30 hours of use. F ailure t o demagnetize
the tape heads can cause an in crease in noise, a loss o f
high frequency sound, and an ina bility to co mplet ely
erase tapes. For deta ils, refer to the in structions of the
demagnetizing cassette.
