Proper Handling
Handle
your
disc
as
shown.
Do
not
drop
the
disc
while
handling.
Hold
the
disc
so
you
will
not
leave
fingerprints
on
the
surface.
If
the
surface
is
scratched,
it
may
cause
the
pickup
to
skip
signal
tracks.
Do
not
affix
tape,
paper,
or
gummed
labels
on
the
disc.
Do
not

Keep Your Discs Clean
Fingerprints,
dust,
or
soil
on
the
surface
could
cause
the
pickup
to
skip
signal
tracks.
For
routine
cleaning,
wipe
the
playing
surface
with
a
clean,
soft
cloth
from
the
center
of
the
disc
to
the
outer
edge.
If
the
surface
is
heavily
soiled,
dampen
a
clean
soft
cloth
in
a
solution
of
mild
neutral
detergent
before
cleaning
the
disc.

Disc Accessories
Various
disc
accessories
for
protecting
disc
surface
and
improving
sound
quality
will
be
available
on
the
market.
However,
most
of
them
will
give
influence
on
thickness
and
diameter
of
the
disc.
Using
such
accessories
will
make
the
disc
specifications
out
of
the
limit
and
may
cause
some
troubles.
So,
do
not
use
them
with
unit.

Caution for New Discs
When
a
newly
purchased
disc
is
inserted,
it
may
be
ejected
after
initial
loading.
This
is
caused
by
small
bumps
around
the
center
hole
and
outside
of
the
disc,
which
prevents stable loading to the correct position.
To
remove
the
bumps,
rub
the
inside
edge
of
the
hole
and
outside
edge
of
the
disc
with
a
ball-point
pen
or
other
such
instrument,
then
insert
the
disc
again.
Please note
The
mechanism
automatically
ejects
such
a
disc
as
a
protective
measure,
and
this
is
not a faulty operation.

Traffic Information Receiving
This model is equipped with traffic information receiving apparatus to be used in
Germany where the traffic information is broadcast in FM. The following is how to use
this unit to receive traffic information broadcasting.
Ty
Z.
Select FM position.
Depress the SDK switch @ and tune to a station. If the station is a traffic information
station, the SK indicator @ will glow and show the reception of a broadcast from a
traffic information station.
NOTE: SK Indicator
When SK signal is received irrespective of the SDK switch position, the SK indicator
will illuminate.
In the SDK mode, stations other than traffic information stations are muted and cut
out. Therefore, it is easy to select a traffic information station.
As the signal of the tuned traffic information station becomes weak, the SK indicator
will extinguish. Then after the lapse of 25 seconds, a rhythmical alarm will sound or
another stronger station will be sought automatically depending on the mode selected.
lf the reception of further traffic information is required, tune in the desired traffic
information station. When received, the alarm will stop and the SK indicator
illuminates. Since the alarm will continue if no signals from any other traffic stations
can be received, release the SDK switch for reception of normal broadcasting.
When the unit is playing a tape or a CD with the SDK switch pushed in and tuned to a
traffic information station, the tape or CD play is interrupted and changed to FM radio
if the pre-tuned station begins a traffic information message. When the message is
over, the unit reverts to tape or CD play automatically.
If traffic information reception is no longer necessary, release the SDK switch for
normal radio reception.
NOTE:
When the SDK switch is pressed and there is no SK signal, ALARM will sound after the
lapse of 25 seconds. Press the SDK switch again to stop it.
