NOTES ON CASSETTES
o The sides of a cassette are marked "A" and •. B ",
When you wish to record or play back side" A", install
the cassette into the cassette compartment with side
•.A" up. When you wish to record or play back side
" B ", install it with side" B" up. .
The letter" A" of the SONY Cassette is embossed to
help distinguish that side of the cassette in a dimly
lighted area.
o Before installing a cassette, remove any slack from the
tape by inserting a pencil into the hub and winding it
until the slack is eliminated.
4
o Tape Cassettes incorporate a convenient safety device
to prevent accidental erasure. (When the recorder is set
in the record mode, previous recordings are automati-
cally erased.)
When the small tabs at the rear of a cassette are broken
out, a safety device will be activated, preventing re-
cording.
To protect side •. A" recording, break out the tab of
side" A".
To protect side" B", break out the tab of side" B "
When the cassette is installed with the tabs broken out,
the REC (record) button cannot be depressed.
To reuse a cassette for recording after the tabs have
been removed, simply cover each slot with a small
piece of cellophane or vinyl tape.
