
Proceed in the following manner if the display remains
blank when the "PLAY/PAUSE" button is pressed ...
With mains operation
First check that the mains adapter is correctly inserted in the
mains socket and the plug on the cable of the mains adapter
has been correctly inserted in the "DC 4.5V" socket on the
left-hand side of the MP3-CD player.
If both have been correctly inserted, then check whether the
mains socket is conducting power by connecting another
electrical appliance to the same mains socket.
With battery operation
Check whether the batteries have been correctly loaded into
the player. If this is the case then check whether the batteries
are discharged or defective.
Rechargeable batteries must be recharged in the battery
compartment of the MP3-CD player. Non-rechargeable bat-
teries must be exchanged or, alternatively, change the MP3-CD
player over to mains operation.

If playback of audio/MP3-CDs does not function or is
faulty, then check whether a film of condensation has formed
on the laser scanning lens of the MP3-CD player.
