Precautions
On salety
• Operate the unit only on 120 V AC, 60 Hz.
• Should any liquid or solid object 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 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.
• As the laser beam used in this compact disc player is
harmful to the eyes, do not attempt to disassemble the
cabinet. Refer servicing to qualified personnel only.
On operation
When the unit is not used, turn the power off, to conserve
energy and to extend the useful life of your unit.
PICKING UP THE UNIT FOR SHOP REPAIR
Important
Since the CD system boasts a wide dynamic range, the
peaks of high level inputs are recorded with high fidelity,
and the noise level is very low.
Do not turn up the volume while listening to a portion with
no audio signals or very low level inputs. If you do, the
speakers may be damaged when a peak level portion is
played.
For detailed safety precautions, see the leaflet ‘‘IMPORTANT
SAFEGUARDS".
If you have any questions or problems concerning your unit,
please contact your nearest Sony dealer.
The white transit key on the bottom exterior of
the unit protects the optical system against
shock during transportation. Before operating
the CD player, be sure to remove the key by
following the instructions on the label, and
store it in a safe place.
Features
The compact disc player is equipped with 5 disc trays
which allow you to choose from a large number and wide
variety of selections.
Any disc at any time
can be played using the DISC SELECT buttons.
When transporting the unit, replace the key in
its original hole and lock it in place.
After being certain the customer’s disc is
unrelated to the problem be sure to remove it
and leave it with the customer.
If the CD player is inoperative the disc can be
removed manually as shown in the illustration.
Multiple functions include:
• PROGRAM play which allows you to play up to 32
selections on any disc in any desired order.
• SHUFFLE play for playing selections in random order.
• REPEAT play for playing a single selection, a single disc, or
all the discs again.
