On safety/power sources
•Should any solid object or liquid fall into the
player, unplug the player, and have it checked
by qualified personnel before operating it any
further.
•Unplug the player from the wall outlet when it
is not to be used for an extended period of
time.
•For battery operation, use four size D (R20)
batteries.
•When the batteries are not to be used, remove
them to avoid damage that can be caused by
battery leakage or corrosion.
•The nameplate indicating operating voltage,
power consumption, etc. is located at the
bottom.
On placement/operation
•Do not leave the player in a location near heat
sources, or in a place subject to direct sunlight,
excessive dust or mechanical shock.
•Do not place anything within 10 mm of the
side of the cabinet. The ventilation holes must
be unobstructed for the player to operate
properly and to prolong the life of its
components.
•Since a strong magnet is used for the speakers,
keep personal credit cards using magnetic
coding or spring-wound watches away from
the player to prevent possible damage from
the magnet.
•If the player has not been used for a long time,
set it in the playback mode to warm it up for a
few minutes before inserting a cassette.
Notes on cassettes
•Break off the cassette
tab from side A or B
to prevent accidental
recording. If you
want to reuse the
tape for recording,
cover the broken tab
with adhesive tape.
•The use of a cassette
with more than 90
minutes of play time
is not recommended except for long,
continuous recording or playback.
If you have questions or problems concerning
your player, please consult your nearest Sony
dealer.
