For customers in
other countries
Note:
Parts and accessories mentioned in this operation ma-
nual other than those shown to the left are not included.
PRECAUTIONS 
Please ensure that the equipment is positioned in a well
ventilated area and ensure that there is at least 10 cm of
free space along the sides, top and back of the equipment.
Do not use oil, solvents, petrol, paint thinners or insec-
ticides on the unit.
Do not expose the unit to moisture, to temperatures higher
than 60˚C (140˚F) or to extreme low temperatures.
Keep the unit away from direct sunlight, strong magnetic
fields, excessive dust, humidity and electronic/electrical
equipment (home computers, facsimiles, etc.) which gener-
ates electrical noise.
Hold the AC power plug by the head when removing it
from the AC socket, since pulling the lead can damage
internal wires.
When cleaning the heads, pinch roller, etc, remove the
AC power plug from the wall socket as the unit contains
high voltages.
Do not remove the outer cover, as this may result in elec-
tric shock. Refer internal service to your local SHARP ser-
vice facility.
Use the unit on a firm, level surface free from vibration,
and do not place anything on the top of the unit.
If the unit does not work properly whilst in use, set the
STAND-BY/ON switch to STAND-BY and then to ON
again.
If a lightning storm is taking place near you, it is suggested
that you disconnect the AC power lead from the AC socket
for safety.
Warning:
The voltage used must be the same as that specified on
this unit. Using this product with a higher voltage than that
which is specified is dangerous and may result in a fire or
other type of accident causing damage. SHARP will not be
held responsible for any damage resulting from use of this
unit with a voltage other than that which is specified.
Condensation
Sudden temperature changes and storage or operation in
an extremely humid environment may cause condensation
inside the cabinet (tape head, etc.).
Condensation can cause the unit to malfunction.
If this happens, leave the power on with no cassette in the
unit until normal playback is possible (about 1 hour).
Volume control
It is advisable to avoid exposure to high volume levels, which
occur whilst turning the unit on with the volume control set-
ting up high, or whilst continually listening at high volumes.

CASSETTE OPERATION 
General information
For playback, use normal or low-noise tape for the best
sound. (Metal or CrO

 tape is not recommended.)
For recording, use only normal tape.
Do not use C-120 tapes, tapes with large diameter reels,
or poor-quality tapes, as they may cause malfunctions.
Before loading a tape into the cassette compartment,
tighten the slack with a pen or pencil.
Cassettes have removable tabs which prevent accidental
recording or erasing from taking place. Removing the tab
will protect the corresponding side from being erased.
Cover the tab holes with adhesive tape to erase or record
again.

To interrupt playback:
Press the PAUSE button during playback.
Press the PAUSE button again to resume playback.

the STOP/EJECT button.
When the end of the tape is reached during the recording,
playback, fast forward or rewind mode, the full auto stop
system is activated and automatically puts the unit into the
neutral (stop) mode.
