Clean the set with a dry cloth. Dont use any clean-ing agents containi

41、ng alcohol, ammonia, benzeneor abrasives as these may harm the set. Place the set on a hard and flat surface so that thesystem does not tilt. Make sure there is good venti-lation to prevent the set overheating. The mechanical parts of the set contain self-lubri-cating bearings and must not be oiled

42、or lubricated.CD player and CD handling If the CD player cannot read CDs correctly, use acleaning CD to clean the lens before taking the setto repair. The lens of the CD player should never be touched! Sudden changes in the surrounding temperaturecan cause condensation on the lens of your CDplayer.

43、Playing a CD is then not possible. Do notattempt to clean the lens but leave the set in awarm environment until the moisture evaporates. Always close the CD and tape door to avoid duston the lens. To clean the CD, wipe in a straight line from thecentre towards the edge using a soft, lint-freecloth.

44、Do not use cleaning agents as they maydamage the disc.Neverwrite on a CD or attach any stickers to it.Tape deck maintenanceTo ensure quality recording and playback of the tapedeck, clean parts A, B and C as shown, once amonth.
