Precautions
Unpacking
On safety
•Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
•Unplug the unit from the wall outlet (mains) if it will not be
used for a long time. To disconnect the cord, pull it out by
grasping the plug. Never pull the cord itself.
•The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet, even if
the unit itself has been turned off.
•AC power cord must be changed only at the qualified
service shop.
On operation
•When the unit is not used, turn the power off to conserve
energy and to extend the useful life of your unit.
•Because of a safety mechanism, the function buttons will
not operate if the cassette holder is not completely closed, if
there is no cassette in the cassette holder, or if a cassette has
been incorrectly inserted into the cassette holder.
On head cleaning
The head and tape path should be cleaned after every ten
hours of operation. Dirty heads and a dirty tape path may
cause:
— loss of high-frequency response
— loss of sound volume
— sound drop-out
Checking the Supplied Accessories
Make sure that the following accessories are included with
your unit.
•Audio connecting cords (2)
Notes on Installation
•Place the unit with the front panel facing you in a location
with adequate air circulation to prevent overheating of the
unit.
•Do not place the unit:
— near heat sources such as radiators or air ducts.
— in places subject to direct sunlight, excessive dust,
mechanical vibration or shock.
— in an inclined position.
— on a rug or other soft surfaces that would block the
ventilation holes on the bottom of the unit.
Do not throw away the carton and the packing
material
They will come in handy when transporting the unit or
shipping it for servicing.
On cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with a mild detergent solution.
Do not use any type of abrasive pad, scouring powder or
solvents such as alcohol or benzine.
If you have any questions or problems concerning your unit,
please contact your nearest Sony dealer.
For the customers in the U.S.A.

Checking the Operating Voltage
•Operate the unit only on 120 V AC, 60Hz (U.S.A. model) or
240 V AC, 50 Hz (U.K. and Australia models).
•Before connecting the unit to an AC (socket) outlet, be sure
that the operating voltage of your unit is identical with that
of your local power supply.
