Precautions
If you have any questions or problems
concerning your stereo system, please
consult your nearest Sony dealer.
Caution
The use of optical instruments with this
product will increase eye hazard.
On operating voltage
Before operating the stereo system, check
that the operating voltage of your stereo
system is identical with the voltage of your
local power supply.
Operating voltage 120 V AC, 60 Hz
On safety
e The stereo system is not disconnected
from the AC power source (mains) as
long as it is connected to the wall outlet,
even if the system itself has been turned
off.
Unplug the system from the wall outlet
(mains) if it is not to be used for an
extended period of time. To disconnect
the cord (mains lead), pull it out by the
plug. Do not pull the cord itself.
Should anv solid object or liquid fall into
the component, unplug the stereo system
and have the component checked by
qualified personnel before operating it
any further,
Should the AC power cord (mains lead)
need to be changed, have it done at a
qualified service shop only.
As the laser beam used in this unit is
harmful to the eyes, do not attempt to
disassemble the cabinet. Refer servicing to
qualified personal only.
On installation
Place the stereo system in a location with
adequate ventilation to prevent heat build-
up in the stereo system.
On condensation in the CD player
component
If the system is brought directly from a cold
to a warm location, or is placed in a very
damp room, moisture may condense on the
lens inside the CD player. Should this
occur, the CD player will not operate.
Remove any CDs and leave the system
turned on for about an hour until the
moisture evaporates.
To save a tape permanently
To prevent a tape from being accidentally
recorded over, break off the cassette safety
tab from side A or B as illustrated. If you
later want to reuse the tape for recording,
cover the broken tab with adhesive tape.
