© WARNING
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 Puls-
armband 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.
©
Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.

LASER PRODUCT
© DANGER: Invisible laser radiation when open.

After servicing and before returning the set to customer
perform a leakage current measurement test from all
exposed metal parts to earth ground, to assure no
shock hazard exists.
The leakage current must not exceed 0.5mA.
AVOID DIRECT EXPOSURE TO BEAM.

SERVICE HINTS
REPAIR POSITION COPPERSIDE
To get access to the copperside of the
printed board assembly proceed as follows:
1. Remove the bottom screws (6x)
2. Lift the bottom-cabinet
3. Supply the unit via external DC-socket
4. Take care that the door switch is closed during
measurements
To get access to the componentside of the
printed board assembly proceed as follows:
1. Remove the bottom screws (6x)
2. Open the CD-door
3. Lift the top-cabinet and put it backwards on the table
4. Supply the unit via the external DC-socket
5. Take care that the door switch is closed during
measurements
REPAIR POSITION COMPONENTSIDE
DISMANTLING THE CD-DOOR
To dismantle the CD-door proceed as follows:
1. Disconnect the membrane keyboard
(flex-foil connector on copperside of printed board)
2. Smoothly bend the bridge of the cabinet downwards as
shown in 1. Take care not to touch the lens
3. Smoothly pull out the right hinge of the CD-door as
shown in 2.
4. Lift the CD-door
Remark: Do not use screwdrivers or tools like that.
Sharp edges could damage hinge or cabinet part.

VAM2103 – DRIVE CLEANING & LUBRICATION
Use an acid-free synthetic grease – i.e. “Tribol 9890-2” or
equivalent.
Before greasing the mechanism first remove the old grease
from the mechanism. Use a cotton swab dipped in alcohol to
clean the mechanism.
Cleaning the mechanism
1. Clean the lower and upper sledge guidance plane
(optical pick-up).
2. Clean the spindle shaft.
3. Clean the area between the worm gear, idler wheel and
clamping spring.
Lubricating the mechanism
1. Put one dot of grease onto the upper sledge guidance
plane on each side of the sledge. Move the sledge to the
inner and outer position to spread the grease.
Put one dot of grease onto the lower sledge guidance
plane on each side of the sledge. Move the sledge to the
inner and outer position to spread the grease.
2. Put one dot of grease onto the spindle shaft on both sides
of the sledge. Move the sledge to the inner and outer
position to spread the grease.
3. Put one dot of grease between the worm gear and the
clamping spring.
VAM2103 – LENS CLEANING
Because the material of the lens is synthetic and coated
with a special anti-reflectivity layer, cleaning must be done
with a non-aggressive cleaning fluid. It is advised to use
“KODAK LENS CLEANER CAT 176 71 36”, available in
normal photo shops.
The actuator is a very precise mechanical component and
may not be damaged in order to guarantee its full function. It
is advised to clean the lens gently (don’t press too hard)
with a soft and clean cotton bud moistened with the special
lens cleaner.
The direction of cleaning must be in the way as indicated in
the picture below.
Before touching the lens it is advised to clean the
surface of the lens by blowing clean air over it in
order to avoid that little particles make scratches on
the lens.
Lubrication of the CD-drive is only necessary in case
of symptom “skipping tracks”.
The reason can be dirt which sticks to the grease or
the grease is getting aged.
