• Do not put any foreign objects in the DC IN

4.5 V (external power input) jack.

• When you are not using the player for a long

time, disconnect all power sources from the
player.

• The nameplate indicating operating voltage,

power consumption, etc. is located at the
bottom of the AC power adaptor (for EA3
only.)

• Use only the supplied AC power adaptor. If

your player is not supplied with it, use AC-
E45HG AC power adaptor. Do not use any
other AC power adaptor.

• To unplug the AC power adaptor from the wall

outlet, grasp the adaptor itself, do not pull its
cord.

• Do not throw the batteries into fire.
• Do not carry the rechargeable battery with

coins or other metallic objects. It can generate
heat if the positive and negative terminals of
the battery are accidentally contacted by a
metallic object.

Certain countries may regulate disposal of the
battery used to power this product.
Please consult with your local authority.

• Keep the lens of the player clean and do not

touch it. If you do so, the lens may be damaged
and the player will not operate properly.

• Do not put any heavy object on top of the

player. The unit and the CD may be damaged.

• Do not leave the player in a location near heat

sources, or in a place subject to direct sunlight,
excessive dust or sand, moisture, rain,
mechanical shock, unleveled surface, or in a car
with its windows closed.

• If the player causes interference to radio or

television reception, turn off the player or move
it away from the radio or television.

• Do not wrap the player in a cloth or blanket

during use as it may cause malfunction or
serious accidents.

Do not use headphones/earphones while
driving, cycling, or operating any motorized
vehicle. It may create a traffic hazard and is
illegal in some areas. It can also be potentially
dangerous to play your headsets at high volume
while walking, especially at pedestrian crossings.
You should exercise extreme caution or
discontinue use in potentially hazardous
situations.

Avoid using headphones/earphones at high
volume. Hearing experts advise against
continuous, loud and extended play.  If you
experience a ringing in your ears, reduce volume
or discontinue use.

Keep the volume at a moderate level. This will
allow you to hear outside sounds and to be
considerate to the people around you.

Clean the lens with a lens cleaning kit KK-DM1.

Use a soft cloth slightly moistened in water or a
mild detergent solution.  Do not use alcohol,
benzine or thinner.

Should any problem persist after you have made
these checks, consult your nearest Sony dealer.
