Precautions
On safety
• Be sure not to short-circuit the terminals of the player with other metallic objects.
• Do not touch the rechargeable battery with bare hands if it is leaking. Since battery liquid may remain
in the player, consult your nearest Sony dealer if the battery has leaked. If the liquid gets into your
eyes, do not rub your eyes as it may lead to blindness. Wash out your eyes with clean water, and
consult a doctor.
Also, if the liquid gets on to your body or clothes, wash it off immediately. If you do not, it may cause
burns or injury. If you get burned or injured by the liquid from the battery, consult a doctor.
• Do not pour water or put any foreign object in the player. Doing so may cause fire or electric shock.
If this occurs, turn off the player immediately, and consult your nearest Sony dealer or Sony Service
Center.
• Do not put the player into the fire.
• Do not take apart or remodel the player. Doing so can result in electric shock. Consult your nearest
Sony dealer or Sony Service Center for exchange of rechargeable batteries, internal checks or repair.
On installation
• Do not put any heavy object on top of the player or apply a strong shock to the player. It may cause a
player to malfunction or damage.
• Never use the player where it will be subjected to extremes of light, temperature, moisture or
vibration. The player may become discolored, distorted or damaged.
• Never leave the player exposed to high temperature, such as in a car parked in the sun or under direct
sunlight.
• Do not leave the player in a place subject to excessive dust.
• Do not leave the player on an unstable surface or in an inclined position.
• If the player causes interference to radio or television reception, turn the player off and move it away
from the radio or television.
• When using the player, remember to follow the precautions
below in order to avoid warping the cabinet or causing the
player to malfunction.
– Make sure not to sit down with the player in your back
pocket.
– Make sure not to put the player into a bag with the
headphones/earphones cord wrapped around it and
then subject the bag to strong impact.
• Do not expose the player to water. The player is not waterproof.
Remember to follow the precautions below.
– Be careful not to drop the player into a sink or other
container filled with water.
– Do not use the player in humid locations or bad weather,
such as in the rain or snow.
– Do not get the player wet.
If you touch the player with wet hands, or put the player in a
damp article of clothing, the player may get wet and this may
cause a malfunction of the player.
• When you unplug the headphone from the player, make sure to hold the headphone plug to unplug it.
Pulling the headphone cord itself may cause damage to the headphone cord.

On heat build-up
Heat may build up in the player while charging if it is used for an extended period of time.
On the headphones
Road safety
Avoid listening with your headphones in situations where hearing must not be impaired.
Preventing hearing damage
Avoid using the headphones at a high volume. Hearing experts advise against continuous, loud and
extended play. If you experience a ringing in your ears, reduce the volume or discontinue use.
Do not turn the volume up high all at once, especially when using headphones.
Turn up the volume gradually so that loud sound will not hurt your ears.
Caring for others
Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate to
the people around you.
Warning
If there is lightning when you are using the player, take off the headphones immediately.
If you experience an allergic reaction to the supplied headphones, stop using them at once and contact
a doctor.
On the use
• When using a strap (sold separately), be careful to avoid hooking it on objects you pass by.
Furthermore be careful not to swing the player by the strap to avoid bumping people.
• Refrain from using the player according to the in-flight announcements during take off or landing in
an aircraft.
• Note that condensation may form temporarily in cases such as when the player is moved quickly
from a low-temperature environment to a high temperature environment or used in a room that has
a heater just turned on. Condensation creates a phenomenon where moisture in the air adheres to
surfaces such as metal panels, etc., and then changes to liquid. If condensation forms in the player,
leave it turned off until the condensation disappears. If you use the player with condensation present,
a malfunction may result.
On the LCD
• Do not push the LCD screen strongly. Color spots may appear or the LCD panel may be damaged.
• If the player is used in a cold place, ghosting may occur. This does not indicate a failure.
• If the player is used in a cold or hot place, contrast may be affected.
On cleaning
• Clean the player’s case with a soft cloth, such as cleaning cloth for eyeglasses.
• If the player’s case becomes very dirty, clean it with a soft cloth slightly moistened with water or a mild
detergent solution.
• Do not use any type of abrasive pad, scouring powder, or solvent, such as alcohol or benzene, as it
may mar the finish of the case.
• Be careful not to let water get into the player from the opening near the connector.
• Clean the headphone plug periodically.
• If you have any questions or problems concerning the player, please consult your nearest Sony dealer.
