I Dolby NR System This deck incorporatesboth the Dolby B-Type and the Dolby C-Type noise reductionsystems,which can be freely selected.The Dolby B-Type NR provides approximately1OdB of noise reductionin the high frequencies.The DolbyC-Type NR achieves a S/N ratio improvementof appr.2OdB in the range from 2 kHz to 8 kHz,where noise is most readilyaudible. For playbackof a tape which was recordedwith Dolby B-TypeNR,the Dolby NR "B" switch has to be pressed.For playback of a tape recorded with Dolby C-Type NR,the "C" switch must be presseo. . The Dolby NR system does not reduce any noise alreadycontainedin the source signal.You should therefore use recordingsources which are as noise-freeas oossible.

[Timer Recording or Playback] This deck incorporatesa timer-startfeature, which enablesyou to make unattended recordingsor start playbackat a preselectedtime with the use of a timer. (1) Establishconnectionsas shown in the chart. (2) Insert the tape to be used for recordingorplaybackand turn on the power to all components. (3) For timer recording,set the recording level to suit the expectedsignal.For timer playback,set the output control to the desired level.Check if all componentsare set up properly. (4) For timer recording,set this deck's timer "Rec". For timer playback,set switch to "Play". the switch to (5) Set the timer to the desiredoperationtime. (6) At the pre-selectedtime,the timer will supply power to the components,and the deck will automaticallystart recordingor playing. . Be sure to set the deck's timer switch to "Off", when the timer recordingor playbackfeature is not desired. I Maintenance ' d and Transport Cleaning very importantto regularilyclean the \/ surfaces of the heads as well as the capstan,pinchrollerand all other parts which come in contact with the tape.Tiny particlessheddedfrom the tape onto these oarts,as well as dust accumulationsetc. becomethe cause of drop-outs,and severely degradefrequencyresponseand wow-andJlutter characteristics. Gleaning Procedure Removethe cassette holder cover. Use cotton{ipped sticks or the like (availablein audio stores,etc.) to carefullyand with very light pressure clean the parts indicatedin white on the illustration.In cases of severe contamination,dip the cotton tip in cleaning fluid. Cleaningis facilitatedif - after removingthe cassetteholder cover - the cover is closed again and the pause switch depressed,thereby raisingthe head ---embly. b pressure roller is very dirty, press the lry switch and clean the roller while it is turning.At this time, be careful that the cotton tip does not get caught betweenthe roller and the capstan.After cleaningthe roller,put the deck into the pause mode again and clean the revolvingcapstan. Erase Head TapeGuide Rec/PB Head CaDstan TapeGuide PressureRoller Be careful not to apply too much force in cleaningas the respectiveparts are critically aligned.Takespecial care not to damagethe tape guides. Do not use too much cleaningfluid and give the cleanedsurfacessome time to dry off completelybefore playinga tape. When you have used cotton-tippedsticks, be careful not to leaveany cotton strands on the cleanedparts. Demagnetizing After a longer period of use,there can be a build-upof residualmagnetismin heads and capstan,etc. Such residualmagnetismcan inducenoiseand impairthe high frequencies during playback.To preventthis, you should demagnetizethese parts about once every 50 hours of use with the optional Nakamichi DM-10 Demagnetizeror another properly designeddemagnetizer.For details on the demagnetizingprocedure,please consult the demagnetizer'sinstructionmanual. . Always switch off the power to the deck before startingthe demagnetizing orocedure. Gleaning the Faceplate This unit shouldbe cleanedonly by wipingit with a soft, dry cloth. Never use alcohol, solvents,ammoniaor abrasivecleaning agents. Lubrication All importantmovingparts of this deck are fitted with long-life,oil-less bearings.Periodic lubricationis thereforenot necessarv.
