No illumination when the radio is switched
off.
A 5
+12 V switching voltage output
(max. 0.5 A)
on blade contact A 5 when the radio is
switched on.
For automatic aerial (extend/retract),
aerial amplifier (operating voltage) etc.
A4
12 V ignition voltage

switch the car radio on and off with the igni-
tion/start switch.
– Connect to terminal 30. The car radio can-
not be switched on and off with the ignition/

To ensure a correct operation of the radio,
this contact must always be connected to
terminal 15 or 30.
A 2
Phone mute connection
for car telephone or CB radio.
The car radio is “muted” when the car tele-
phone or CB radio is in operation.
The display indicates ”
PHONE
”, see page 16,
EXPERT functions.
For this, the blade contact A 2 must be
connected from the mute output of the tele-
phone/CB radio to earth!

If you wish to connect only two
loudspeakers:
Use the adapter supplied (Fig.

) to combine
the four 7 W loudspeaker outputs to two 20 W
outputs. For this, connect the 20 W adapter to
the socket B (Fig.
+
).
Connection of the front speakers (see above)
is not changed but the rear sockets remain
free.
Do not electrically connect speaker
connections to each other and do not
connect to chassis!
Aerial
The car radio is designed for aerials with an
impedance of 75
Ω
to 150
Ω
. Extended aerial
cables, e.g. for aerials at the rear of the car,
may impair reception.

Installation and Removal
Audio- cassettes
are subjected to high temperatures during car
radio operation. Therefore use only high-
quality heat-resistant C 60 and C 90 Cr0
2
cas-
settes from name-brand manufacturers.
Radio reception conditions
VHF (FM) reception
Reception conditions change constantly while
you are driving.
Mountains, buildings or bridges can all
disturb reception.
This is particularly true when you are farther
away from the station.
Radio Data System (RDS)
RDS is an information system the signals of
which are broadcast along with the FM radio
station programme.
Programme service
With RDS programmes, you see the abbrevi-
ated name of the programme in the display,
e.g. "
BAYERN 3
"
which stands for Bayerischer Rundfunk –
Programme 3.
Please note that RDS programmes can have
different regional stations and programme
names.
Alternative frequencies
An RDS programme is broadcast by several
stations, each with a different broadcast
frequency (alternative frequencies).
You select an RDS programme and your car
radio will always tune to a station with an
alternative frequency giving best reception of
the same RDS programme.
Enhanced Other Network (EON)
This functions allows you to listen to traffic
announcements even if you have tuned in an
RDS programme without traffic announce-
ments.
Prerequisite:
The radio station that is broadcasting your
selected RDS programme with EON broad-
casts an additional RDS programme which
offers traffic announcements.
Traffic announcement standby
in the case of RDS programmes with EON if
”TP” is activated in the dispaly and the RDS
programme tuned to remains audible.
Switching TP on/off
Press the
¡
TP
button.
TP on: ”TP” in the display is surrounded by a
frame.
If a malfunction should occur
please consult your dealer.
In the Federal Republic of Germany, Grundig
car radios can be exchanged by your dealer
on request for a works-tested exchange unit
in the event of a defect occuring.
Please note:
It is a condition for your dealer to participate
in this exchange system that the guarantee
seal on your car radio is not damaged.
Care and maintenance
The front panel of the car radio must only be
cleaned with a soft, dust-absorbent, anti-static
cloth. Polishing and cleansing agents may
damage the surface of the trimplate.
The tape head must be free of tape dust in
order to avoid losses in the treble tones
during playback. Therefore you should clean
the tape head with a cleaning cassette after
every 50 …100 hours of operation.
Important Information
The radio cannot be switched on
Insert the left-hand
ÄÄ
control knob once
again.
Press and hold down the
¡
IO
button for at
least 1 second.
Check the fuse at the back of the radio, see
page 21). If it is defective, take the radio to
your specialized dealer.
Security LED
If the security LED does not function, let
check the connections of the radio by a spe-
cialist (see page 17/Connection A4).
Select the EXPERT control level (see page
13).»

Poor reception
Are you in an area of bad reception conditions
(eg., underground car park, tunnel, valley,
etc.)?
In this case, reception will surely improve
when changing the location.
If reception gets nevertheless not better, the
aerial or aerial lead might be damaged. Let
check your radio by a specialist.
Reception is frequently interrupted
Your are in an area of very bad reception con-
ditions. Here it may happen that pauses occur
when the radio tries to change to alternative
frequencies. In this case, the AF function
should be switched off (see page 6).
CD does not play
Note the error messages shown in the display
and read the operating instructions of the CD
changer.
MAGAZINE
CD magazine missing or not
locked in.
MECHANIC
CD changer – mechanical defect.
NO CD
CD magazine empty.
NO COMMU
Data transmission interrupted.
SURFACE
CD incorrectly inserted or
distorted data transmission.
TOO HOT
CD changer overheated.
One loudspeaker is dead
Check the setting of the FADER and BALANCE
controls and correct if necessary. If this
brings no result, let check the loudspeaker
leads and the loudspeakers by a specialist.
