ESD

WARNING

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.

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

WAARSCHUWING

ATTENTION

I
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.

D

AVVERTIMENTO

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.

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.

“Pour votre sécurité, ces documents
doivent être utilisés par des spécialistes agréés, seuls habilités à réparer
votre appareil en panne”.

NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.

Le norme di sicurezza esigono che l’apparecchio venga rimesso
nelle condizioni originali e che siano utilizzati i pezzi di ricambio
identici a quelli specificati.

Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina

DK Advarse !
"After servicing and before returning set to customer perform a
leakage current measurement test from all exposed metal parts to
earth ground to assure no shock hazard exist. The leakage current
must not exceed 0.5mA."

Notes:
– To avoid magnetic interference, do not position
the front speakers too close to your TV set.
– Allow adequate ventilation around the DVD Mini
Hi-Fi System.

Place the front left and right speakers at equal
distances from the TV set and at an angle of
approximately 45 degrees from the listening
position.

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.

IMPORTANT!
The type plate is located on the rear of
the system.

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.

Use the composite video cable (yellow) to
connect the system’s VIDEO jack to the video
input jack (or labeled as A/V In, Video In,
Composite or Baseband) on the TV set.
To listen to TV channels through this system, use
the audio cables (white/red) to connect AUX
IN (L/R) jacks to the corresponding AUDIO
OUT jacks on the TV set.
Deactivate Progressive Scan through SYSTEM
MENU. See page 31, Using the Setup MenuUsing Progressive Scan to improve image quality.

Using Video In jack (CVBS)

IMPORTANT!
– You only need to make one video
connection from the following options,
according to the capabilities of your TV
system.
– S-Video or Component Video
connection provides higher picture
quality. These options must be available
on your TV set.
– Connect the system directly to the TV
set.

(or labeled as Pr/Cr Pb/Cb Y or YUV) on the TV
set.
To listen to TV channels through this system, use
the audio cables (white/red) to connect AUX
IN jacks to the corresponding AUDIO OUT

MENU. See page 31, Using the Setup MenuUsing Progressive Scan to improve image quality.

Using an accessory RF modulator

IMPORTANT!
– If your TV set only has a single
Antenna In jack (or labeled as 75 ohm or
RF In), you will need a RF modulator in
order to view the DVD playback via TV.
See your electronics retailer or contact
Philips for details on RF modulator

For better FM stereo reception, connect an
outdoor FM antenna to the FM ANTENNA
terminal.

Connect the supplied MW loop antenna to the

Use Service Testprogram. By selecting the TUNER TEST test frequencies will be stored as preset frequencies automatically.
2) RC network serves for damping the IF-filter while
adjusting the other one.
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)

1) If sensitivity of frequency counter is too low adjust to max. channel separation
3) For AM RF adjustments the original frame antenna has to be used!

Input Function

CLK

System clock

Active on the positive going edge to sample all inputs.

CS

Chip select

Disables or enables device operation by masking or enabling all inputs except
CLK, CKE and DQM

CKE

Clock enable

Masks system clock to freeze operation from the next clock cycle.
CKE should be enabled at least one cycle prior to new command.
Disable input buffers for power down in standby.

A0 ~ A11

Address

Row/column addresses are multiplexed on the same pins.
Row address : RA0 ~ RA11,
Column address : (x4 : CA0 ~ CA9, x8 : CA0 ~ CA8 , x16 : CA0 ~ CA7)

BA0 ~ BA1

Bank select address

Selects bank to be activated during row address latch time.
Selects bank for read/write during column address latch time.

RAS

Row address strobe

Latches row addresses on the positive going edge of the CLK with RAS low.
Enables row access & precharge.

CAS

Column address strobe

Latches column addresses on the positive going edge of the CLK with CAS low.
Enables column access.

WE

Write enable

Enables write operation and row precharge.
Latches data in starting from CAS, WE active.

DQM

Data input/output mask

Makes data output Hi-Z, tSHZ after the clock and masks the output.
Blocks data input when DQM active.

DQ0 ~ X15

Data input/output

Data inputs/outputs are multiplexed on the same pins.

VDD/VSS

Power supply/ground

Power and ground for the input buffers and the core logic.

VDDQ/VSSQ

Data output power/ground

Isolated power supply and ground for the output buffers to provide improved noise
immunity.

N.C/RFU

No connection
/reserved for future use

This pin is recommended to be left No Connection on the device.
