INSTALLATION
If your car is equipped with ISO connectors, simply insert them in the connectors of the car radio. If not, you can use an adaptor cable (Refer to the table on the separate installation manual). Ensure all cables are installed so that they cannot be damaged by sharp edges or moving parts.
PREPARATION
Voltage and polarity: The set must be connected to a 12V car battery with negative terminal to earth (car chassis). Installation in vehicles not fulfilling these requirements could result in malfunction, damage or fire.

Warning: To prevent short-circuiting, disconnect the negative car battery terminal until the set has been mounted and connected (fig.1 See separate installation card).
CONNECTOR A (fig.2)
Power supply connections
- Red wire A7 : Connect to a permanent 12V supply. This is the main power supply. Ensure this connection can handle a current of 10A.
- Yellow/red wire A4 : Connect to a switched 12V supply (switched on/off by car ignition).
- Brown wire A8: Connect to earth (car chassis). This connection set up will enable you to make full use of the ON/OFF LOGIC function of this set limiting the use of the set to 1 hour after removal of the ignition key. If this feature does not appear to be functioning as expected you may require an adaptor cable (EA6259). See reverse of installation card.
• Electronic antenna/Motorised antenna

Connect pin A5 to the power supply for an electronic antenna or the control wire for the relay of an automatic motorised antenna. Use the small connector supplied.

Do not use this connection for the supply lead of the aerial motor!
- Pilot light

When the car headlights are switched on, the backlight to the power key remains illuminated (even when the radio is switched off).
Connect pin A6 to the dashboard illumination wiring of the car. Use the small connector provided.
Note : In certain car (e.g. VW Passat) the dashboard illumination is dimmed by a digitally modulated signal (PWM - Pulse Width Modulation). This PWM signal can disturb the illumination display of the car radio. In this case, connect pin A6 to the switch signal of the low beam headlight. Please consult your car dealers for more information.
CONNECTOR B (fig.3)
Loudspeakers (use 4 ohm loudspeakers only)
- Do not connect any of the loudspeaker leads to earth or directly to a booster/amplifier without high level input or via an external fader! You can connect the loudspeaker leads directly to an amplifier with high level input.
- Connecting 4 loudspeakers:
Front Rear
| Left+ Green [B5] White [B7] | ||
| Left- Green/black [B6] White/black [B8] | ||
| Right+ | Grey [B3] | Blue [B1] |
| Right- | Grey/black [B4] | Blue/black [B2] |
Complies with 21 CFR 1040.10
MOUNTING
METAL SLEEVE (fig.6)
- Install the metal sleeve (dimension 182x53 mm) in the dashboard.
- Fix metal sleeve into place by pressing the metal tags outwards using a screwdriver.
CONNECTING THE RADIO (fig.7)
- Ensure the battery is disconnected.
- Insert aerial plug E into aerial socket (good reception is only possible with a good aerial). Fix antenna adaptor if needed. Use hook (J) on back of set to secure fixing.
- Insert power supply connector A into socket A'.
- Insert loudspeaker connector B into socket B'.
MOUNTING RADIO
This radio can be properly installed either from conventional Front Mounting or Rear Mounting, depending on DIN/JIN opening of the car's dashboard.
FRONT MOUNTING
- Slide the radio into the metal sleeve until the springs at either side of the radio snap into the openings of the sleeve (fig.8).
- Finally reconnect the negative car battery terminal (fig.9).
REMOVING RADIO (using the two U-brackets supplied)
- Remove the trimplate around the front panel.
- Insert both U-brackets into the holes on the front of the set until they lock. Pull out the radio (fig.10).
REAR MOUNTING (fig.11)
- Remove the trimplate around the front panel and the side springs.
- Select a position where the screw holes of the mounting bracket and the screw holes of the radio become aligned and tighten the screws at 2 places on each side.
- Only use M5 screws that are not longer than 6mm.
REPLACING FUSE (fig. 7)
- Replace with a 10A blade-type fuse. The new fuse must be of exactly this value and type otherwise the set will not be adequately protected. Ignoring this procedure may lead to damage to the set, which will invalidate the guarantee.
INTERFERENCE SUPPRESSION
- Most modern cars have sufficient interference suppression. If you experience interference generated by the car, consult your dealer.

TROUBLE SHOOTING
There may be times when you suspect that your car radio is not functioning as you would expect it to. Before calling for service, please read the operating / installation instructions and review the following checklists. You may find that an apparent malfunction can easily be rectified.
If you still have to send your set for service, always send the complete set. Do not try to open the set to service it yourself.
Audio
Set does not function. No Display.
- Check fuse (set and car) and connections.
Set functions but no sound?
- Adjust the volume of the set.
- Check fader and balance settings.
- Check aerial and its connection.
The sound from the speakers is reduced automatically.
- A built-in safety circuit prevents the temperature in the set from exceeding a certain level.
- Wait for the temperature to decrease before increasing the volume.
Radio
Cannot tune to desired station?
- Check that the aerial is fully extended and properly connected.
- Check that the negative terminal (brown lead) is connected to earth (car chassis).
- Desired station is too weak, try Manual Tuning.
Poor tuner reception?
- In some cars (e.g. VW and Seat) there is an active aerial on the roof that needs a 12 Volt supply. Please ask your dealer to check whether a 12 volt is supplied to the antenna.
Display shows frequency (not station name).
- Set is tuned to non-RDS station.
Radio mutes momentarily while display shows 'SEARCH' and station name/frequency alternately.
- Set is checking a list of Alternative Frequencies (AF) for the tuned radio station as reception is
weak. In case no AF is transmitted for the tuned station, switch off AF via the 'SETUP'.
Display shows 'NO TA', and set beeps at intervals.
- The tuned station becomes too weak to enable the reception of Traffic Announcements. Use search tuning to find another station.
- If the TA mode is switched on, search tuning only selects stations which enable the reception of Traffic Announcements.
Cassette
Display shows 'ERROR'.
- Check cassette for faults
Cassette playback lacks high-notes or loss of one channel.
- Clean cassette player tape head.
Tape Slack
- Check and make sure any slack in the tape is taken up before inserting the tape into the unit. A loose tape can get caught in the mechanism and cause damage to the unit and tape itself. Tighten the tape by using a pencil or a similar instrument into the spindle hole and turn until all slack has been taken up.
