Notes:
• Choose the mounting location where
the unit will not interfere with the
normal driving function of the driver.
• Before finally installing the unit,
connect the wiring temporarily and
make sure it is all connected up
properly and the unit and the system
work properly.
• Use only the parts included with the
unit to ensure proper installation.
The use of unauthorized parts can
cause malfunctions.
• Consult with your nearest dealer if
installation requires the drilling of holes
or other modifications of the vehicle.
• Install the unit where it does not get in
the driver’s way and cannot injure the
passenger if there is a sudden stop,
like an emergency stop.

horizontal, the unit might not give its
optimum performance.
• Avoid installing the unit where it would
be subject to high temperature, such
as from direct sunlight, or from hot air,
from the heater, or where it would be
subject to dust, dirt or excessive
vibration.

player connected to the unit through
the AUX IN jack, the front panel will
change from State 2 to State 1.
If there is a portable audio player
connected to the unit through the AUX
IN jack, when switch the ignition key
to “ACC OFF”, the front panel will
remain State 2.
USING THE FRONT PANEL
1. When switch the ignition key to “ACC
ON”, the panel of the unit will change
from State 1 to State 2 (see below),
the hidden panel will turn up.
2. Press (power) button to turn on the
unit. Then press (eject) button, the
panel will turn down to horizontal
position (see State 3).

OPERATION
a) TA SEEK or TA ALARM
- TA SEEK mode:
When newly tuned station does
not receive TP information for
several seconds, the radio
retunes to next station which has
not the same station (PI) as the
last station, but has the TP
information.
When TP information gets lost at
the current station for retune time
which is set by RETUNE SHORT
(30 sec.) or RETUNE LONG (90
sec.), the radio start to retune to
next same PI station.
When same PI station does not
catch in 1 cyclic search, the radio
retunes to next station with TP
information.
- TA ALARM mode:
When this mode is selected, any
automatic retune mode is not
activated.
Only double beep sound (ALARM)
is output.
When newly tuned station does
not have TP information for
several seconds, beeps come
out.
When TP information gets lost at
the current station for retune time,
the beep sound is out-putted.
When newly tuned station has not
RDS signal, “PI SEEK”is
suppressed somewhat.
b) PI SOUND or PI MUTE
While AF switching is implemented
in C201 station, AF can switch to
100 MHz, which is non genuine AF
(where, different PI with same AF) in
short “DIP”.
If a car cruises that critical area back
and forth, an oscillation
phenomenon can be occurred,
because the different PI code can
be received from 100 MHz with
“XXX”PI.
The car radio has special procedure
to reduce even this kind of
unavoidable situation however there
is a limit to be escaped from this
serious case perfectly.
In that serious case, 2 mode is
selectable as follows:
- PI SOUND mode:
When above different PI sound
(DIP) is heard once in a while, the
DIP’s sound will be heard for a
short time.
- PI MUTE mode:
Under above same situation, a
mute sound will be heard for a
short time.
c) RETUNE L, RETUNE S mode
The initial time of automatic TA
search or PI search mode is
selected.
When PI information is not caught
for retune time, the radio start to
retune to next same PI station.
When same PI station does not
catch 1 cyclic search, the radio
goes to last station and waits for
several minutes until PI code is
received.
- RETUNE L mode:
Selected as 90 seconds.
- RETUNE S mode:
Selected as 30 seconds.
d) MASK DPI or MASK ALL mode
The AF frequency (which has
different PI or NO RDS signal with
high field strength) is masked during
checking PI when the unit searches
AF. The unit doesn’t search this AF
(DIP) for few minutes. In the case
of the AF of NO RDS signal with
100 90
98
100
PI : C201 PI : XXX

high field strength, if the real AF is
wrongly masked as DIP by some
interference, the unit hesitates to
search real Afs. For this reason, the
unit has the user option (MASK DPI)
which doesn’t mask the AF of NO
RDS signal with high field strength.
In MASK DPI mode, the wrong
sound or long mute (according to PI
SOUND or PI MUTE) can be heard
from the AF station which has NO
RDS signal and of which the field
strength is higher than that of the
currently tuning AF (station).
But, these phenomenon are rare
and the user will hardly hear the
wrong sound in whole Europe.
- MASK DPI mode:
Masked only the AF which has
different PI.
- MASK ALL mode:
Masked the AF which has
different PI and NO RDS signal
with high field strength.
e) BEEP 2’ND, BEEP ALL, BEEP OFF
mode
The situation of beep sound is
selected.
The 3 mode is selected as also by
VOL( / ) / (11&12) button.
- BEEP 2’nd mode:
The beep is only generated when
all allowed double key is pressed
long (1 sec).
e.g.
When preset button (14) is
pressed.
When BND/LOU button (13) is
pressed.
When AMS button (18) is
pressed.
- BEEP ALL mode:
The beep is generated when
every key is pressed.
- BEEP OFF mode:
The beep is disabled.

temporarily to radio mode.
Temporary switch over to an EON
linked station when EON detects a
traffic announcement on that other
program. If the volume level was
under the threshold point it will be
raised to the threshold point.
But the user changed the volume
level which was more than the
threshold point (min. TA volume
level), it will be set to the last level.
When TA mode is on, TA of
individual segment is turned on.
When a TP station is received, TP of
individual segment is turned on.

Note:
A. Notes on discs:
•Attempting to use non-standard shape
discs (e.g. square, start, heart) may
damage the unit. Be sure to use round
shape CD discs only for this unit.
•Do not stick paper or tape etc., onto
the label side or the recording side of
any discs, as it may cause a
malfunction.
•Dirt, dust, scratches and warping discs
will cause misoperation.
B. Notes on CD-Rs (recordable
CDs)/CD-RWs (rewritable CDs):
•Be sure to use discs with following
marks only for the unit to play:
•The unit cannot play a CD-R and
CD-RW that is not finalized.
(Please refer to the manual of your
CD-R/CD-RW recorder or CD-R/
CD-RW software for more information
on finalization process).
•Depending on the recording status,
conditions of the disc and the
equipment used for the recording,
some CD-Rs/CD-RWs may not be
played on this unit. (See *)
* To have more reliable play back, please
see following recommendations:
- Use CD-RWs with speed 1x to 4x
and write with speed 1x to 2x.
- Use CD-Rs with speed 1x to 8x and
write with speed 1x to 2x.
- Do not play a CD-RW which has
been written for more than 5 times.
C. Notes on MP3 files (MP3 Version
Only):
•The disc must be in the ISO9660 level
1 or level 2 format, or Joliet or Romeo
in the expansion format.
•When naming a MP3 file, be sure the
file name extension is “.MP3”.
•For a non-MP3 file, even though the
file name extension is “.MP3”, the unit
cannot recognize it.
D. Notes on multi session disc:
•If the first track of the first session is
audio CD data, then the unit will play
only the audio CD data.
•When the first track of the first session
is not audio CD data, but MP3 file is in
the disc, then only MP3 files will be
played back and other data (including
CD data) is skipped.
•For recording status other than above
2 situations, the unit may not play
properly. Be sure to avoid this case.
