Philips CDR795, CDR796 User Manual

For servicing CDR79x the set has to be divided into two parts:

1. Except for the CD-R/W module all workshops can repair the set on component level.

The Switched Mode Power Supply unit will be exchanged completely in case of a failure.

2.The CD-R/W module can only be repaired on component level with the help of ComPair.
With this tool diagnosing of the set can be done in an interactive way. In this tool also the adjustment procedure has
been implemented. The adjustment is absolutely necessary in case the CDR-Main Board and/or CD drive (CDR Loader)
is disconnected from the matched production combination.

Only designated workshops can perform these repairs!

Please send the complete set to the designated workshop.

© 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 Puls­armband 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.

After all other connections have been made, connect

the power cord to the power outlet.

Setup information

Place the unit on a flat,hard and stable surface.Do not

position the unit on top of other equipment that might

heat it up (e.g. receiver or amplifier), If the unit is placed in a

cabinet,make sure to leave at least 3.5 cm (1.5 inches) free

around the unit to prevent overheating. Active mobile

phones near the unit may cause malfunctions.

Connections general

Never make or change connections with the power

supply switched on.

For playback the following outputs are present:

– Analog output (ANALOG OUT L/R)

– Digital coaxial output (DIGITAL OUT)

– Digital optical output (OPTICAL OUT)

For external recording the following inputs are present:

– Analog input (ANALOG IN L/R)

– Digital coaxial input (DIGITAL IN)

– Digital optical input (OPTICAL IN)

These inputs can be connected to the corresponding

output(s) of your amplifier/receiver or directly to the

corresponding output(s) of the external appliance.

It is not possible to connect a turntable directly to

ANALOG IN L/R. If you wish to use a turntable with

the unit, you have to connect an amplifier/receiver to

ANALOG IN L/R on the CD player/recorder. Then

connect the turntable to the amplifier.

The connections you make will depend upon the

possibilities your audio equipment offers and how you are

going to use the unit. Please refer to the user manuals for

your audio equipment first.

We recommend doing analog recording only if digital

recording is not possible. Digital recording will result in

better sound quality.

If possible, always make both digital and analog connections.

In this way you can always make analog recordings when

digital recording is not possible.

BRIEF OPERATING INSTRUCTIONS

Direct digital optical connection

This connection is required for direct recording from any

digital audio equipment with a digital optical output (e.g.

CD player or DVD player).

1 Remove the dust caps from the digital optical input of the

CD player/recorder and from the digital optical output of

the external appliance. Keep the caps in a safe place.

2 Use a digital optical cable to connect the optical output of

the external appliance with OPTICAL IN on the

CD player/recorder. Make sure you insert both plugs fully,

until a click is heard.

Digital coaxial connections via a digital receiver

If you have a receiver with digital coaxial in- and outputs,

these connections allow you to make digital recordings

from various sources connected to the receiver.

Use a coaxial cable to connect the digital coaxial input of

the receiver with DIGITAL OUT on the CD player/recorder.

Use another coaxial cable to connect the digital coaxial

output of the receiver with DIGITAL IN on the

CD player/recorder.

The type plate is located on the rear of the unit.

1 Check whether the power voltage as shown on the type

plate corresponds to your local power voltage. If it does

not, consult your dealer or service organization.

2 Make sure all connections have been made before

switching on the power supply.

3 Connect the power cable supplied to AC MAINS ~ and to

the power outlet.This switches on the power supply.

When the unit is switched to standby, it is still consuming

some power. To disconnect the unit from the power

completely, remove the power plug from the power

outlet.

Analog connections

These connections are required for playback and recording

via an amplifier/receiver, equipped with analog in- and

outputs.

1 Connect the red plug of the supplied audio cable (cinch) to

the red jack ANALOG IN R and the white plug to the

white jack ANALOG IN L on the CD player/recorde.r:

2 Connect the other end of the audio cable to the analog

outputs of the amplifier/receiver (CDR OU T, TAPE OUT,

AUX OUT, REC OUT, etc.).

3 Connect the red plug of the supplied audio cable (cinch) to

the red jack ANALOG OUT R and the white plug to the

white jack ANALOG OUT L on the CD player/recorder:

4 Connect the other end of the audio cable to the analog

inputs of the amplifier/receiver (CD-R,TAPE IN,AUX,

PLAY IN, etc.).

5 Connect all other components of your system (tape deck,

CD player, tuner,turntable,etc.) via their analog outputs to

the appropriate analog inputs of the amplifier/receiver

(CD IN,TUNER IN, AUX IN,PHONO IN, etc.).0Recording can be done now with any appliance connected

to an analog input of the amplifier/receiver: Press INPUT on

the CD player/recorder repeatedly to select the analog

input.

ANALOG IN is displayed.

How to connect if the analog output on the

amplifier/receiver is already being used (occupied)

Most amplifiers/receivers have multiple analog output

connections (TAPE,VCR,…), but some amplifiers/receivers

have only 1 analog output. In case you have already hooked

up a tape deck (DAT recorder or MD recorder) to this

output you will have to change the existing connections.

1 Disconnect the analog connections from the tape deck to

the amplifier/receiver.

2 Connect the CD player/recorder (see steps 1–4 in the

previous chapter).

3 Connect the analog outputs of the tape deck to any free

analog inputs (AUX, CD) on the amplifier/receiver: You can

now playback your tape or record from your tape deck on

CD.However, it is no longer possible to record on tape.

Digital connections

Direct digital coaxial connection

This connection is required for direct recording from any
