Precautions
Electronic Book Player
On Safety
• The display is made of glass and may
break if it is bent.
• Since the display is made of glass, do
not push the player from above with your
elbow, etc. or place heavy objects on it
such as books. The glass used for
the display may break.
• As the laser beam used in this
player is harmful to the eyes, do not
attempt to disassemble the casing.
Refer servicing to qualified personnel
only.
• Do not insert anything in the DC IN 6V
(external power input) jack.
• When the player is used with the AC power adapter, do not wrap
the unit in a cloth, blanket, etc. If you do so, the temperature
inside and outside the player may rise considerably, resulting in
malfunctioning of the player or serious accidents.
• Should any solid object or liquid fall into the player, disconnect
the power source and have the player checked by qualified
personnel before using it any further.
• Do not drop the player as a malfunction may result.
On power sources
• Use alkaline batteries (not supplied) or mains in your home or
office.
• For AC operation: Use the AC power adapter supplied with this
player. Do not use any other AC power adapters as they may
cause malfunction.
• After operating the unit with an AC power adapter, disconnect
the AC power adapter from the mains if the set is not to be used
for an extended period of time. The [POWER] switch on the
player does not turn the AC adapter off.
On installation
Never expose the player to:
- heat sources such as radiators or air ducts.
- direct sunlight.
- excessive dust.
- moisture or rain.
- mechanical vibration or shock.
- inclined position.
- a dashboard or leave it in a car parked in sunlight.
On condensation
If the player is brought directly from a cold location to a warm one,
or is placed in a very damp room, condensation may occur on the
lens inside the player, causing it to malfunction. If this happens,
remove any electronic book inside the player, then leave the
player in a warm place for a few hours until the condensation
evaporates.
About the temperature
The bottom of the player may get warm. This is not a malfunction.
The AC power adapter also gets warm. However, if the AC power
adapter gets excessively hot, disconnect it and have it checked by
your nearest Sony dealer.

Except for maintenance or troubleshooting, do not remove an
electronic book disc from its caddy; otherwise the disc may get
scratched or dirty.
Do not store electronic books:
• in direct sunlight.
• in a place subject to high temperature.

When you are not going to use an electronic book for a long time,
remove it from the player.
