For recording, make sure to use special audio discs only.
These discs are marked with “Digital Audio” and the logos
shown below.

There are two different types of audio discs for the use on
this CD recorder:

– 

CD-Audio Recordable (CDR) discs

These discs can be recorded on once and play
in all standard CD players and CD recorders,
when they are finalized.

– 

CD-Audio ReWritable (CDRW) discs

These discs can be recorded on, erased and
re-recorded many times and play in CDRW
compatible CD players and CD recorders,
when they are finalized.

– All Philips CD players and CD recorders with 

the sticker shown here are CDRW compatible.

To ensure proper working of the set we recommend the use of
Philips audio CDR and audio CDRW discs only.

Note: Do not use a computer CDR or CDRW as recording will

not work properly!

In certain countries including the UK and certain
Commonwealth countries, use of the product (or CD-
Recorder) as shown or suggested in this user manual
may require the permission of copyright holders.

For playback on this CD changer and CD recorder you can use
following audio discs:

– All pre-recorded audio CDs

– All audio CDR and audio CDRW discs

Notes:
– Do not try to play a CD-ROM, CD-I or CDV!
– CDR(W) discs, which are recorded on a computer can only

be used when they are correctly treated according the
audio standard (IEC958: Consumer part). Single session
only!

Clean the set with
a soft, slightly dampened lint-free
cloth. Do not use any cleaning agents
as they may have a corrosive effect.

Do not expose the set,
batteries or CDs to humidity, rain,
sand or excessive heat (caused by
heating equipment or direct sunlight).

The lenses may cloud over when the set is suddenly moved
from cold to warm surroundings. Playing a CD(RW) is not
possible then. Leave the set in a warm environment until the
moisture evaporates.

For recording it is very important to use dust and scratch free
discs.

To take a CD(RW) out of its box 
easily, press the centre spindle while
lifting the CD(RW). Always pick up a
CD(RW) by the edge and put it back
after use. Never write on a CD or
attach a sticker to it. Write only on 
the printed side of a CDR or CDRW,
and only with a soft felt-tipped pen.

To clean a CD(RW), wipe it in a straight
line from the centre toward the edge
using a soft, lint-free cloth.
A cleaning agent may damage the disc!
