Safety and general mainte- nance

Place the set on a hard and flat surface so that the system does not tilt.

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

The apparatus shall not be exposed to dripping or splashing.

Adequate ventilation with a minimum gap of 15cm between the ventilation holes and sur- rounding surfaces is necessary to prevent heat build-up.

The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains, etc..

No objects filled with liquids, such as vases, shall be placed on the appartus.

No naked flame sources, such as lighted can- dles, should be placed on the apparatus.

The mechanical parts of the set contain self-lubricating bearings and must not be oiled or lubricated.

To clean the set, use a soft dry cloth. Do not use any cleaning agents containing alcohol, ammonia, benzene or abrasives as these may harm the housing.

CD player and CD handling

If you do not intend to use the CD clock radio for a long time, withdraw the power cord from the wall outlet.

The lens of the CD player should never be touched!

Sudden changes in the surrounding tempera- ture can cause condensation to form and the lens of your CD player to cloud over. Playing a CD is then not possible. Do not attempt to clean the lens but leave the set in a warm environment until the moisture evaporates.

Always shut the CD door to keep the CD compartment dust-free.To clean, dust the compartment with a soft dry cloth.

To clean the CD, wipe in a straight line from the center towards the edge using a soft, lint- free cloth. Do not use cleaning agents as they may damage the disc.

Never write on a CD or attach any stickers to it.

If a fault occurs, first check the points listed below before taking the set for repair.

If you are unable to remedy a problem by following these hints, consult your dealer or service centre.
