All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wristband with resistance. Keep components and tools at this potential.

f ATTENTION

Tous les IC et beaucoup d´autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévite pourrait être considérablement écourtée par le fait qu´aucune précaution nést prise à leur manipulation. Lors de réparations, s´assurer de bien être relié au même potentiel que la masse de l´appareil et enfileer le bracelet serti d´une résistance de sécurité. Veiller à ce que les composants ainsi que les outils que l´on utilise soient également à ce potentiel.

d WARNUNG

Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kann die Lebensdauer drastisch reduzieren. Sorgen Sie dafür, daß Sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential.

ñ WAARSCHUWING

Alle IC´s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

i AVVERTIMENTO

Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevità potrebbe essere fortemente ridatta in caso di non osservazione della più grande cauzione alla loro manipolazione. Durante le riparationi occorre quindi essere collegato allo stesso potenziale che quello della massa delápparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.

Brief Operating Instruction

Preparations

FM Antenna

¶ For better FM stereo reception, connect an

outdoor FM antenna to the FM ANTENNA

terminal.

C Speakers Connection

Front Speakers

Connect the speaker wires to the SPEAKERS

(FRONT) terminals, right speaker to "R" and left

speaker to "L", coloured (marked) wire to "+"

and black (unmarked) wire to "-".

1

2

● Fully insert the stripped portion of the speaker

wire into the terminal as shown.

Notes:

– For optimal sound performance, use the

supplied speakers.

– Do not connect more than one speaker to any

one pair of

+

/

-

speaker terminals.

– Do not connect speakers with an impedance

lower than the speakers supplied. Please refer to

the SPECIFICATIONS section of this manual.

Optional connections

The optional equipment and connecting cords

are not supplied. Refer to the operating

instructions of the connected equipment for

details.

Subwoofer Out connection

Connect the subwoofer to the SUBWOOFER

OUT terminal. The subwoofer reproduces just

the low bass sound effect (explosions or the

rumble of spaceships, for example).

Connecting other equipment to your

system

Connect the audio left and right OUT terminals

of a TV, VCR, Laser Disc player, DVD player or

CD Recorder to the AUX/CDR IN terminals.

Note:

– If you are connecting equipment with a

monaural output (a single audio out terminal),

connect it to the AUX/CDR IN left terminal.

Alternatively, you can use a “single to double” cinch

cable (still be monaural sound).

Digital Out connection

Connect this digital output when recording on

any audio equipment with digital input (CD

Recorder, Digital Audio Tape [DAT] deck, Digital

to Analogue Conver ter and Digital Signal

Processor, for example). Use a cinch cable to

connect the DIGITAL OUT terminal to the

digital input terminal of the equipment.

Inserting batteries into the

remote control

Insert two batteries (Type R06 or AA) into the

remote control with the correct polarity as

indicated by the + and - symbols inside the

battery compar tment.

CAUTION!

– Remove batteries if they are exhausted

or will not be used for a long time.

– Do not use old and new or different

types of batteries in combination.

– Batteries contain chemical substances, so

they should be disposed off properly.

Preparations

Rear connections

The type plate is located at the rear of the

system.

For users in the U.K.: please follow the

instructions on page 2.

A Pow er

Before connecting the AC power cord to the

wall outlet, ensure that all other connections

have been made.

WARNING!

– For optimal performance, use only the

original power cable.

– Never make or change connections with

the power switched on.

To avoid overheating of the system, a safety

circuit has been built in. Therefore, your

system may switch to Standby mode

automatically under extreme conditions. If

this happens, let the system cool down

before reusing it.

B Antennas Connection

Connect the supplied AM loop antenna and FM

antenna to the respective terminals. Adjust the

position of the antenna for optimal reception.

AM Antenna

¶ Position the antenna as far as possible from a TV,

VCR or other radiation source.

SERVICE POSITIONS & REPAIR HINTS

1) During repair it is possible to disconnect the ECO6 Tuner board, ETF8 Tape Module and/or 3DTC Module completely unless the fault is suspected to be in that area. This will not affect the performance of the rest of the set.

2) Use Service position A for repairs on Combi or Mains Board.

3) Use Service position B for repairs on Tuner or 3DTC electronic.

4) Use Service position C for repairs on the ETF8 Tape module.

Note: The flex cables are very fragile, care should be

taken not to damage them during repair. After repair, be very sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occur.

Radial Error Triggered when the radial servo is off-track for a certain time during play.

Sledge In Error The sledge did not reach its inner position (inner-switch is still close) before approximately 6 Sec. have passed by. Inner-switch or sledge motor problem.

Sledge Out Error The sledge did not come out of its inner position (inner-switch is still open) before approximately 250 mSec. have passed by. Inner-switch or sledge motor problem.

Jump-offtrack error Triggered in normal play when the jump destination could not be found within a certain time.

Subcode Error Triggered when a new subcode was missing for a certain time during play.

PLL Error The Phase Lock Loop could not lock within a certain time.

Turntable Motor Error Generated when the CD could not reached 75% of speed during startup within a certain time. Disc motor problem.

Focus Search Error The focus point has not been found within a certain time.

The active lower carriage does not come to the end position within a certain time. This can happen when the switches are defective, or when the carriage is blocked in between two end positions (example: 2 disc in one carriage). The time-out is approximately 5 seconds.

The drawer could not enter the inside position and is opening again. This can happen if the drawer is blocked such that it cannot go fully inside, or if the drawer switch is defective and never closes.

The active upper carriage does not come to the end position within a certain time. This happen when the switches are defective, or when the carriage is blocked in between two end positions (example: 2 disc in one carriage)/ The time-out is approximately 5 Sec.

The drawer could not enter the outside position and is stopped at its blocked position. This can happen if the drawer is blocked such that it cannot go fully outside, or if the drawer switch is defective and never opens.

3DTC Module

(Basic version)

Layout stage .5

10-2

The following steps have to be done when replacing the CD mechanism:

1. Disconnect flexfoil from old CD drive

2. Put a paperclip over contacts of flexfoil to short-circuit the contacts (fig.1)

3. Remove old CD drive

4. Remove paperclip from flexfoil

5. Connect flexfoil to new CD drive

6. Remove ESD-protection (solder joint) from laserunit (see below)

7. Position new CD drive in its studs

CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE CD DRIVE ELECTRONICS WHEN CONNECTING A NEW CDM MECHANISM. THAT´S WHY, BESIDES THE SAFETY MEASURES LIKE

• SWITCH OFF POWER SUPPLY

• ESD PROTECTION ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN.

WARNING

fig.1

Attention: The laser diode of this CD drive is protected against ESD by a solder joint which shortcircuits the

laserdiode to ground. For proper functionality of the CD drive this solder joint must be removed after connection the drive to the set.
