Precautions
If you have any questions or problems
concerning your stereo system, please
consult your nearest Sony dealer.
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.
On safety
• 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 any solid object or liquid fall into
a 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 personnel only.
On installation
• Place the stereo system in a location with
adequate ventilation to prevent heat
buildup in the stereo system.
• Do not install the unit in an inclined
position.
• Do not install the unit in locations where
it is;
– Extremely hot or cold
– Dusty or dirty
– Very humid
– Vibrating
– Subject to direct sunlight
On condensation in the CD player
component
If the system is brought directly from a cold
to a warm one, or is placed in a very damp
room, moisture may condense on the lens
inside any CDs 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.
When you are using a type II (CrO
cassette, be careful not to cover the detector
slots which allow the tape player to
automatically detect the type of tape.
TYPE II
Detector slots
In case color irregularity is observed
on nearby a TV screen.
With the magnetically shielded type of
speaker system, the speakers can be
installed near a TV set. However, color
irregularity may still be observed on the TV
screen depending on the type of your TV
set.
If color irregularity is observed...
Turn off the TV set once, then turn it on
after 15 to 30 minutes.
If color irregularity is observed
again...
Place the speakers farther away from the
TV set.
