• The supplied AC power adaptor is not

water resistant. To prevent shock hazard,
avoid using the player near water during
AC operation.

• Cover the DC IN 4.5 V jack and i jack

with the attached rubber caps when
nothing is connected to these jacks. If the
inside of the jacks are contaminated with
water or sand, rust may develop and cause
trouble.

Notes

• Since the unit is airtight, you may not be able to

open the lid when there is a sudden change in air
pressure inside the unit. This happens when the
unit is transported on a plane or moved from a
warm place to a cold place. In this case, open the
rubber cap on the DC IN 4.5 V jack.

• To prevent water from leaking in, the buckle is

designed to be slightly stiff. Be careful not to
catch a fingernail on the buckle when unfastening
the lid.

Do not hold the player with the buckle
by itself. Doing so may damage the
unit.

Maintenance

To clean the casing

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

To clean the headphones/
earphones plug

Keep the plug of your headphones/earphones
clean to obtain optimum sound. Wipe it with
a dry, soft cloth.

To remove any dust or sand
from the rubber packing

Any sand or dust on the rubber packing will
prevent the lid from shutting tightly, and
water may leak in. Brush off the dust once in
a while.
We recommend the replacement of the
rubber packing every year which is available
optionally at an authorized Sony service
facility.
