CONTROLS

OPERATE PRECAUTIONS

O

Operate this machine in a level horizontal position
only.

Avoid setting this machine on a vacuum tube
amplifier, etc. which generates heat, or Operating
the unit in extremely hot or cold places. Also
avoid blocking the ventilator.

lleads should be kept clean and demagnetized at
all times.

This machine is designed for utilization of low
noise tape as standard. The use of ordinary tape
will result in inferior performance.

Before using a cassette tape. check to confirm
whether tape slack exists. As tape slack causes
the tape to twist or tangle around the pinch wheel
and capstan. take up slack if necessary.

As the base of (--l10 tapes are thin and easily
damaged. they are not recommended for use with
this machine.

Recording cannot he made on the leader tape.
Therefore. when using a new cassette tape. be sure
to forward the tape slightly so that the leader
tape is not iii the head path.

Tapes which have been stored in a hot moist place
for a period of time or cassette tape with bent
cases should not be. used. Such tape may curl or
have greasy places on the tape altering tape speed
and preventing proper performance. Always store
tapes in a cool. dry place.

Do not touch the tape with your fingers as high
frequency signals cannot be recorded in places
which are not clean on the tape.

When using a tape recorded with the Dolby process.
it is necessary to depress the Dolby NR Switch
at playback time also. Keep the Dolby NR Switch
at OFF position at all times except during Dolby
recording or playback.

Cassette tapes are equipped with a break-out tab
for both A and B sides. When these tabs have been
removed to protect an important recording. no fur-
ther recording can be made on the tape unless
the cavities are plugged or covered with a piece
of tape.

I-I'AK l.I'.VI"I. INDICATOR __

At nonnal recording. VU Meter response is usually accurate. but when
pulsive signals enter. such as signals from percussion instruments. etc..
response is slow and lower than actual volume is registered. This peak
level indicator acts as a warning device by lighting at excessive input.
Became. for recording with the least noise possible. it is advantageous
to keep the recording level as high as possible not to exceed the level
at which distortion occurs due to excessive input. for best recording
results. the level range in which this liglii flickers at largest input parts
only is most ideal.

prevent over-recording and cut distortion when recording at a high
volume level. Especially effective when recording from microphones at
close range.

Setting the Dolby NR Switch to ON position activates the Dolby circuit

to raise low level signals before they are recorded and lowers them

by preciesly the same amount during playback. thus reducing the ex-

traneous and superimposed noise. resulting in the reduction of tape bin

to a completely inaudible level.

' when using a tape recorded With the Dolby process. it is necessary
that the switch be set to ON position at playback also.
