Sony PS-4750 - PRECAUTIONS

PRECAUTIONS
@ Should any liquid or solid object fall into the cabinet, unplug
the set and have it checked by qualified personnel before operat-
ing it any further.
@ Unplug the set from the wall outlet when it will not be used
for an extended period of time.
@No lubrication is required for this player, since it employs a
motor shaft of self-lubricated metal.
eClean the cabinet and dust cover periodically with a soft dry
cloth. Do not use solvents such as alcohol, benzine or thinner,
since they will damage the finish.
@When the rubber mat is dirty, wipe it softly with a soft cloth
slightly dampened with water.
NOTES ON LOCATION
ePlace the turntable on a level surface.
e@ Avoid placing the set near electrical appliances (such as tele-
vision, hair dryer, fluorescent lamp) which may cause hum or
noise.
eAvoid any vibration (such as from speakers, slamming of
doors, etc.).
@Keep the set away from direct sunlight, extreme of tempera-
ture or excessive dust and moisture.
@ Allow five inches clearance behind the set so that the cover
can be opened. (See @ on page 2.)
ADAPTATION TO THE LOCAL MAINS
SUPPLY
The PS-4750 has a voltage selector of 110 V, 127 V, 220V or
240 V with a transparent cover. The voltage selector is located
at the bottom of the set.
Before connecting to mains supply, check that the voltage
selector indicates the same voltage as your local mains supply.
If it is not the same, the voltage selector setting may be
changed. (See @ on page 2.)
1. Before changing the voltage selector setting, check that the
PS-4750 is disconnected from the mains supply.
2. Remove the transparent cover.
Loosen the red-painted screw on the cover, but do not remove
it from the cabinet. Remove the other screw on the cover.
Then turn the cover around the red-painted screw so that you
can unplug the selector.
3. The voltage selector can be reset as follows.
Pull out the ac voltage selector plug and reinsert it so that
the top arrow mark of the plug points to the proper voltage
marking.
4. After changing the voltage, reset the cover.
A line frequency change is not necessary since the PS-4750
has a dc servo-controlled motor.
