© 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.

1 Connect the speaker cables to the MC W770.

Use the supplied speakers only . Using other speakers

can damage the set or the sound quality will be

negatively affected.

2 Connect the AM/MW antenna.

3 Connect the FM antenna.

4 If you want to connect an additional appliance , use a cinch

cable to connect the audio inputs of the MC W770 to the

audio outputs of the additional appliance.

5 Check whether the mains voltage as shown on

the type plate cor responds to your local mains

voltage . If it does not, consult your dealer or

service or ganisation.

Make sure all connections hav e been made

before switching on the mains supply.

Connect the AC power cord supplied to

LEAD FREE PRODUCED SET

This set is manufactured with lead-free
production technology. This is also indicated by
the PHILIPS-lead-free logo you find on the
printed boards.

The set is produced with lead-free solder-alloy as well as
with lead-free sub-parts. It can be considered as lead-free.
Due to this fact some rules have to be respected by the
workshop during a repair:

• Use only lead-free soldering-tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder-paste is required,
please contact the manufacturer of your solder-equipment.

• Use only adequate solder tools applicable for lead-free
soldering-tin.

• Adjust your solder tool so that a temperature around 217°
– 220° is reached at the solder joint.

• Do not mix lead-free soldering-tin with leaded soldering-tin.
This would lead to unreliable solder joints.

• On our website http://www.atyourservice.ce.philips.com
you find more information to

– aspects of lead-free technology
– BGA-de-/soldering, heating-profiles of BGAs used in

Philips-sets, and others.
