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.
CLASS 1 LASER PRODUCT 3122 110 03420

Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina näkymättömälle laserisäteilylle. Älä katso säteeseen!
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."

This DVD Mini Hi-Fi System is compatible with both NTSC and PAL. For the playback of a DVD disc on this DVD Mini Hi-Fi System, the color systems of the DVD, TV set and DVD Mini Hi-Fi System should match.
Turn on the TV set and set to the correct VideoIn channel. You should see the blue Philips DVD background screen on the TV set. ➜ You may go to channel 1 on your TV set, then press the channel down button repeatedly until you see the Video In channel. ➜ Or, you can use the TV remote control to select different video modes. ➜ Or, set TV to channel 3 or 4 if you are using an RF modulator. Selecting the color system that matches your TV set
Press DISC (DISC 1•2•3) on the front panel (or press DISC 1/2/3 on the remote control).
IMPORTANT! – Make sure you have completed all the necessary connections. (See Connections – Connecting TV set)
Step 3: Setting the TV set
Notes: – The clock will be cancelled when the power cord is disconnected or if a power failure occurs. – During clock setting, if no button is pressed within 10 seconds, the system will exit the setting mode and go back to it’s previous status.

Step 5: Setting language preference
Preparations
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.
Step 1: Placing speakers

– – Black Black
+ White Red
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.

PREPARATIONS AND CONTROLS
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.
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.
Step 3: Connecting TV set
Use the component video cables (red/blue/ green) to connect the system’s Pr Pb Y jacks to the corresponding Component video input jacks (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 jacks on the TV set.
Using component Video In jack (Pr Pb Y)
Connections
Use the S-Video cable (not supplied) to connect the system’s S-VIDEO OUT jack to the SVideo input jack (or labeled as Y/C or S-VHS) 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 jacks on the TV set.
Using S-Video In jack
Connections
Use the composite cable (yellow) to connect the system’s VIDEO jack to the video input jack on the RF modulator. Use the RF coaxial cable (not supplied) to connect the RF modulator to your TV’s RF jack.
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 availability and operations.

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!
