General information on laser devices

CLASS 1

LASER PRODUCT

Your system is a CLASS 1 LASER PRODUCT. This means that the laser is designed in such a way as to ensure that the maximum permissible emission value cannot be exceeded under any circumstances.

Caution:

If operating devices or methods other than those specified here are employed, it may lead to dangerous exposure to emissions.

This device emits laser radiation. Because of the danger of eye injuries, the unit may only be opened or serviced by trained personnel.

If settings other than those specified here are employed or other procedures are carried out, this may lead to dangerous radiation exposure.

Troubleshooting

Not every kind of picture or sound interference is caused by a defect in your hi-fi system. Defects can also be caused by leads having been accidentally pulled out, damaged discs and worn out batteries in the remote control. If the following measures do not rectify the problem, consult your authorised dealer.

Due to the difference in quality of the recording media and the quality of the recording itself, it can occasionally happen that a home-made CD cannot be read. This does not indicate a malfunction of the hi-fi system.
