Safety information● Before operating the system, check that the operating voltage indicated on the typeplate (or the voltage indication beside the voltage selector) of your system is identical with the voltage of your local power supply. If not, please consult your dealer.● Place the system on a flat, hard and stable surface.● Place the system in a location with adequate ventilation to prevent internal heat build-up in your system. Allow at least 10 cm (4 inches) clearance from the rear and the top of the unit and 5 cm (2 inches) from each side.● The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains, etc.● Do not expose the system, batteries or discs to excessive moisture, rain, sand or heat sources caused by heating equipment or direct sunlight.● No naked flame sources, such as lighted candles, should be placed on the apparatus.● No objects filled with liquids, such as vases, shall be placed on the apparatus.● Don’t expose the system to dripping or splashing.● Install this unit near the AC outlet and where the AC power can be reached easily.● The lens may cloud over when the system is suddenly moved from cold to warm surroundings, making it impossible to play a disc. Leave the system in the warm environment until the moisture evaporates.● The mechanical parts of the set contain self lubricating bearings and must not be oiled or lubricated.● When the system is switched to Standby mode, it is still consuming some power. To disconnect the system from the power supply completely, remove the AC power plug from the wall socket.
