Careless handling duringrepair can reduce life drastically.When repairing, make sure that you are connected with thesame potential as the mass of the set via a wristband withresistance. Keep components and tools at this potential.f ATTENTIONTous les IC et beaucoup dautres semi-conducteurs sontsensibles aux dcharges statiques (ESD).

AC MAINS - inlet for mains lead.CAUTIONUse of controls or adjustments or performance of pro-cedures other than herein may result in hazardousradiation exposure or other unsafe operation.POWER SUPPLYWhenever convenient, use the AC power supply toconserve battery life. Make sure you remove thepower plug from the set and wall outlet before inserting batteries.Batteries (not included) Insert 6 batteries, type R-14, UM-2 or C-cells,(preferably alkaline) with the correct polarity. (See 6)IMPORTANT! Incorrect use of batteries can cause electrolyte leakage and will corrode the compartment or causethe batteries to burst. Do not mix battery types: e.g. alkaline with carbonzinc. Only use batteries of the same type for theset. When inserting new batteries, do not try to mix oldbatteries with the new ones.Batteries contain chemical substances, sothey should be disposed of properly.Using AC Power1.Check if the AC power supply, as shown on thetype plate located on the bottom of the set,corresponds to your local power supply. If it doesnot, consult your dealer or service centre.2.Connect the mains lead to the wall socket.3.To disconnect the mains supply, unplug the setfrom the wall socket.The type plate is located on the bottom of theset.This set complies with the radio interferencerequirements of the European Community.For users in the U.K., please follow the boxedinstructions Important notes. on this sheet.BASIC FUNCTIONSSwitching on and off and selecting function1.To switch on, adjust the POWER slider to select:CD, MW (AM), FM or TAPE function, and operate the respective function controls.2.To switch off, adjust the POWER slider to selectTAPE/OFF and make sure all the cassette keysare released.Note : The DBB setting, tuner presets and the volume level (maximum to 20) will be retained in thesets memory.Adjusting volume and sound (See 2)1.Adjust the volume with the VOLUME controls.

Clean the set with a dry cloth. Dont use any clean-ing agents containing 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 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. 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. 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. Use a cotton bud slightly moistened with alco-hol or a special head cleaning fluid to clean the deck.1.Open the tape door.2.PressPLAY 1and clean the roller C.3.Press PAUSE;and clean the heads A, and thecapstan B.4.After cleaning, press OPENSTOP 0 9.Note:Cleaning of the heads can also be done by playing acleaning cassette through once.No sound /powerVolume not adjusted Adjust the VOLUMEMains lead not securely connected Connect the AC mains lead properlyBatteries exhausted/ incorrectly inserted Insert (fresh) batteries correctlySevere radio hum or noiseElectrical interference: set too close to TV, VCR orcomputer Move the set to increase the distancePoor radio receptionWeak radio signal FM: Adjust the FM telescopic aerialnocd indicationCD badly scratched or dirtyReplace/ clean CD, see MaintenanceLaser lens steamed up Wait until lens has clearednFcd indicationCD-R(W) is blank/ not finalizedUse a finalized CD-R(W)dAtA indicationCD contains non-audio filesPress SEARCHor once or more to skip to aCD audio track, instead of the data fileThe CD skips tracksCD damaged or dirty Replace or clean CDSHUFFLE or PROG is active Switch off SHUFFLE / PROGPoor cassette sound qualityDust and dirt on the heads, etc. Clean deck parts, see MaintenanceUse of incompatible cassette types (METAL orCHROME) Only use NORMAL (IEC I) for recordingRecording does not workCassette tab(s) may be broken Apply adhesive tape over the missing tab spaceAutostoreAutostore automatically starts programming radio stations from preset 1.
