HOW TO HANDLE CASSETTE TAPES
CHECK CASSETTE BEFORE USE
Bear in mind the following points before loading cassette tapes
Is the tape loose, or is some of the tape out-
side the cassette?
If some of the tape is proiecting outside the cassette shell or if it is
loose, it may not enter between the capstan and pinch relier This will
prevent the tape from being supplied or damage the tape itself tn
cases like these, insert a pencil into the reel hole and take up the slack
(Fig A}
Some cassette tapes come with a plastic or thick paper stopper which
prevents tape slack Remove this stopper when loading the tape and
replace it after having used the cassette
What are the accidental erasure prevention
tabs for?
A cassmte is provided with these tabs so that important or otherwise
valuable recordings will not be erased accidenta!ly
When the tab (Fig B} on the cassette shell is broken out with the tip
of a screwdriver, it will nol be possible to depress the recording (REC}
button, so valuable recordings wilt not be erased in error
To re-record a cassette on which tabs have been broken out, simply
apply a piece of adhesive tape over the tab areas, as shown in Fig C
NOTE
The accidental erasure prevention tabs are located at the top left
t on both sides A and B (t or 2), so that material on eac7_ side can be
prevented from being erased in error
TIPS ON USING CASSETTE TAPES
• Leader tape (which does not allow sound to be recorded over it} is
provided at the beginning of a cassette tape Start recording after
allowing the tape to run for about 5 seconds so that the leader tape
clears the recording he_d
Do not leave a cassette tape exposed to the environment Store
the cassette in its case so that dust and dirt do not adhere to the
tape after use, and so that the tape is prevented from becoming
slack Choose a location which is not exposed to the effects of
magnetism, dust, dirt and oil for storing the tapes
, Because C-120 tapes are so thin, they easily jam in the pinch roller
and capstan, and they are susceptible to other trouble such as ir-
regular winding Try net to use them with this unit

NOISE REDUCTION SYSTEM
This unit features a dual noise reduction system (Dolby NR B and C
systems}
Dolby NR system
The Dolby NR system is designed to reduce the amount of tape hiss
(mainly in the treble componenls}, During recording, the high_pitcl_ed
pianissimo sounds which are most characteristic of audible noise are
boosted, and during playback these boosted sections only are at_
tenuated so that the tape sound is returned to normal As a result, the
noise is attenuated by an amount equivalent to the boosting in the tre-
ble range,
The Dolby NR B system serves to reduce noise in the treble range, it
cuts tape hiss and expands the dynamic range The Dotby NR C
system is even more effective than the B in reducing noise as it cuts
the noise from the mid-range on
NOTE
When a rape has been recorded using the Dolby NR B or C
system, make sure that the same DOLBY NR switch position is
selected when it is played back
