WARNING
GB
All ICs and many other semi-conductors 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 wrist wrap with resistance.
Keep components and tools also at this
potential.
F
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler 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.

ESD
D
WARNUNG
Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.
WAARSCHUWING
NL
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
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 riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.
F
Les normes de sécurité exigent que l’appareil soit remis à l’état
d’origine et que soient utiliséés les piéces de rechange identiques
à celles spécifiées.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten. Der Original zustand des Geräts darf nicht verändert werden;
für Reparaturen sind Original-Ersatzteile zu verwenden.

Before connecting the AC power cord to the
wall outlet, ensure that all other connections
ha
ve been made.
WARNING!
–For optimal performance, use only the
original po
wer cable.
–Never make or change any 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 (not available for all versions).
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.
Preparations
FM Antenna
For better FM stereo reception, connect an
outdoor FM antenna to the FM AERIAL (FM
ANTENNA) terminal.
C
Speakers Connection
Front Speakers
Connect the speaker wires to the SPEAKERS
terminals, right speaker to "RIGHT" and left
speaker to "LEFT", colored (mar ked) wire to
"+" and black (unmarked) wire to "-".
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 connection
The optional equipment and connecting cords
are not supplied. Refer to the operating
instructions of the connected equipment for
details.
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 terminals.
Note:
– If you are connecting equipment with a mono
output (a single audio out terminal), connect it to
the AUX left terminal. Alternatively, you can use a
“single to double” cinch cable (the output sound still
remain mono).

PREP ARATIONS AND CONTROLS
Important notes for users in the
U.K.
Mains plug
This apparatus is fitted with an approved 13
Amp plug. To change a fuse in this type of plug
proceed as follows:
1
Remove fuse cover and fuse.
2
Fix new fuse which should be a BS1362 5 Amp,
A.S.T.A. or BSI approved type.
3
Refit the fuse cover.
If the fitted plug is not suitable for your socket
outlets, it should be cut off and an appropriate
plug fitted in its place.
If the mains plug contains a fuse, this should
have a value of 5 Amp. If a plug without a fuse
is used, the fuse at the distribution board
should not be greater than 5 Amp.
Note: The severed plug must be disposed of to
avoid a possible shock hazard should it be
inserted into a 13 Amp socket elsewhere.
How to connect a plug
The wires in the mains lead are coloured with
the following code: blue = neutral (N),
brown = live (L).
¶ As these colours may not correspond with the
colour markings identifying the terminals in
your plug, proceed as follows:
– Connect the blue wire to the terminal
marked N or coloured black.
– Connect the brown wire to the terminal
marked L or coloured red.
–Do not connect either wire to the earth
terminal in the plug, marked E (or e) or
coloured green (or green and yellow).
Before replacing the plug cover, ma ke cer tain
that the cord grip is clamped over the sheath
of the lead - not simply over the two wires.

TROUBLESHOOTING
Cleaning the Cabinet
Use a soft cloth slightly moistened with a mild
detergent solution. Do not use a solution
containing alcohol, spirits, ammonia or abrasives.
Cleaning Discs
When a disc becomes dirty,
clean it with a cleaning cloth.
Wipe the disc from the centre
out.
Do not use solvents such as
benzene, thinner, commercially
available cleaners, or antistatic
spray intended for analogue records.
Cleaning the disc lens
After prolonged use, dirt or dust may
accumulate at the disc lens. To ensure good
playback quality, clean the disc lens with Philips
CD Lens Cleaner or any commercially available
cleaner. Follow the instructions supplied with
cleaner.
Cleaning the Heads and the Ta pe Paths
To ensure good recording and playback quality,
clean the heads
A
, the capstan(s)
B
, and
pressure roller(s)
C
after every 50 hours of
tape operation.
Caution: Do not rotate the heads during
cleaning.
Use a cotton swab slightly moistened with
cleaning fluid or alcohol.
You can also clean the heads by playing a
cleaning tape once.
Demagnetising the heads
Use a demagnetising tape available at your
dealer.
Maintenance
WARNING
Under no circumstances should you try to repair the system yourself, as this will invalidate the
warranty. Do not open the system as there is a risk of electric shock.
If a fault occurs, first check the points listed below before taking the system for repair. If you
are unable to remedy a problem by following these hints, consult your dealer or service center.
Problem Solution
CD OPERATION
“NO DISC” is displayed. –Insert a disc.
– Check if the disc is inserted upside down.
–Wait until the moisture condensation at the lens
has cleared.
– Replace or clean the disc, see “Maintenance”.
– Use a finalised CD-RW or CD-R.

RADIO RECEPTION
Radio reception is poor. – If the signal is too weak, adjust the antenna or
connect an external antenna for better reception.
–Increase the distance between the Micro HiFi
System and your TV or VCR.
TAPE OPERATION / RECORDING
Recording or playback cannot be made. –Clean deck parts, see “Maintenance”.
– Use only normal (IEC I) tape for recording.
“CHECK TAPE” is displayed. – Apply a piece of adhesive tape over the missing
tab space.
The tape deck door cannot open. – Remove and reconnect the AC power plug and
switch on the system again.
