Suggestions
forSafety
I Usea standardAC wall outlet
1. Usefiom an AC power source of high voltage, such as for
an air conditioner, is very dangerous'
Thereis the possibility
thata fire might
be caused
by making
such a connection.
2. A DC power source cannot be used.
Be sureto checkthe powersource
carefully,
especially
on a
ship or other place where DC is used.
I Grasp
the
plug
when
disconnecting
the
power
supply cord
1, wet hands are dangerous.
A dangerous
electric
shock
mayresult
iftheplug
istouched
by
wet hands.
2. Never place heavy items on top of the power supply cord'
and never lorce it to bend sharply.
I Place
theunitwhere
it will bewell
ventilated
Placethis unitat least10 cm (4")awayfrom wallsurfaces,
etc.
I Avoidplaces
such as the following:
In direct sunlight or in other placeswhere the temperatureis
high.
ln places where there is excessive vibration or humidity.
Suchconditions
mightdamage
the cabinet
and/or
othercompo-
nent partsand therebyshorten
the unit'sservicelife.
I Besure
toplace

surface
lf the surfaceis inclined,a malfunction
may result.
I Neverattempt
to repairorreconstruct
thisunit
A serious electricshock might occur if this unit is repaired,
disassembled
or reconstructed
by unauthorized
persons,
or if the
internal

unit includestwo types of Dolby noise-reduction
systems,
the
DolbyB NR-typeand C NR{ype, and DolbyHX PRO headroom
extensionsystem.
f Dolby B-typenoise-reductionsystem
Noiseis reducedto about one-third.

When recordingsare made at the same recording
leveland by
using differentbrands of tape, even though the type of tape
(regular
or "normal" tape, for example)is used, when these
recordingsare played back the listenermay notice that the
high-frequency
soundsare
not
asdistinctononetapeortheother,
etc.
Thereasonthatsuchdifferences
may
benoticed is becausethere
aredifterences
ofthefrequencyresponse
(particularly
inthetreble
range) between cassette tapes of the various manufacturers of
taoe.
Although,
for recordings
andplayback
in which
a noise-reduction
system is used, it is the principle
for such recordingsthat the
recordingandplaybackprocesses beatthesamerecordinglevel,
if,asa result ofthe
reason
describedabove,thereisadifferenceof
the frequencyresponse,there will result a difference in the
processes
for recordingandfor playback,
andcorrect
recordings
and playback cannotbe accomplished.
In order to overcomethis problem,this unit includesa bias-
adjustmentcontrol
(for
compensation
of the frequency response)
so that the most appropriate recording can be made.
