Before Operation
NOTES ON CASSETTE TAPE
• Before loading a cassette tape, take up the slack in the
tape to prevent it from becoming entangled around the
capstan.
• After the recording has been finished, remove the tab to
prevent the recorded contents from being erased or
recorded on accidently.
For side B
• To rerecord after tabs have been removed, cover with
adhesive tape.
• Do not cover the tape detection holes for chrome
(CrO
) tape.
2
• Do not store the tapes in direct sunlight or near
equipment that generates heat. Keep the tapes away
from any magnetic fields.
• Do not touch the tape surface and store the tapes in their
cases after use. Dust can cause contamination of the
heads resulting in noise.

PRINCIPLE OF DOLBY B NR SYSTEM
The Dolby NR system functions so that it automatically
increases recording levels of medium and high
frequencies when the recording signal level is lower
than the specified level(encoding), and automatically
reduces the output level to the normal level during
playback(decoding). In this way, the tape hissing noise
is remarkably reduced without affecting the sound
quality. The Dolby B NR system used in your Cassette
Deck improves S/N ratio by about 5 dB at 1 kHz and
about 10 dB at 10 kHz.
Manufactured under lincense from Dolby Laboratories.

CLEANING THE HEAD SECTION
Clean the head section about every 10 hours of use
with a commercially available head cleaning tape.
• For better recordings, you should clean the
head section before every recording.
• After cleaning the head section, do not load a
tape until the cleared section is completely dry.
DEMAGNETIZING THE HEAD
When the recording/playback head is magnetized, the
sound quality will be deteriorated.
In this case, demagnetize the head using a
commercially available demagnetizer.
AUTO TAPE SELECTOR
The type of tape loaded is detected automatically by
the auto tape selector and recording bias and
equalization are set automatically according to the
characteristic of that tape such as normal or
chrome(CrO
) tape.
