Consumer Line to find the nearest service centre. The number

incorrect connection. To solve this problem, carefully read the

Recorder maintenance
The appliance can be cleaned using a damp leather cloth.
Do not use cleaning agents such as alcohol, methylated spirits,
ammonia or scouring agents.
Disc maintenance
As is the case with pre-recorded CDs, fingerprints and spots on the
disc will not directly affect the signal. Depending on how dirty the
disc is, the clarity of the reflected signal may deteriorate to such an
extent that the sound quality diminishes.
• To write on the printed side of a CD-R, use a felt-tipped pen;
never use a pen with a hard point (such as a ball-point)
because this could damage the recording.
• Keep the shiny side of the disc clean. Use a non-fluffy cloth and
always wipe in a straight line from the centre to the edge.
• Never use cleaning agents for conventional records.
• Never use other cleaning agents or scouring agents.
• Never leave the disc in direct sunlight and do not subject the
disc to extremely high temperatures.
