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

NR "B" switch has to be pressed.For
playback of a tape recorded with Dolby
C-Type NR,the "C" switch must be

For good recordings,it is essentialto
maintaina high signal-to-noiseratio. lf the
record level is set too low tape hiss will
impairthe playbacksound quality.On the
other hand,setting the record leveltoo
high will cause distortion.Referto the

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

Do not use too much cleaningfluid and
give the cleanedsurfacessome time to

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

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.
