Never attempt to disassemble, repair, or alter the workstation on any occasion other
than described in this manual. Failure to follow this instruction may cause an electric
shock or fire as well as malfunctions of the workstation.
Do not look into the CD-ROM drive.
A laser beam used in the CD-ROM drive is harmful to the eyes. Do not look into or insert
a mirror into the drive while the drive is powered. If a laser beam is caught in your eyes,
you may lose your eyesight (the laser beam is invisible).
Do not remove the lithium battery.
Your workstation contains the lithium battery. Do not remove the battery. Placing the
lithium close to a fire or in the water may cause an explosion.
When the workstation does not operate appropriately due to the dead lithium battery,
contact your sales representative. Do not disassemble the workstation to replace or
recharge the battery by yourself.

the peripherals.
Make sure to power off the workstation and disconnect the power plug from a power
outlet before cleaning or installing/removing internal optional devices. Touching any
internal device of the workstation with its power cord connected to a power source may
cause an electric shock even of the workstation is off-powered.
Disconnect the power plug from the outlet occasionally and clean the plug with a dry
cloth. Heat will be generated if condensation is formed on a dusty plug, which may
cause a fire.
Warning label
WARNING LABELS
The warning label is attached to components with
possible danger or their vicinity in your workstation to
inform the user that a hazardous situation may arise
when operating the workstation. (Do not intentionally
remove or damage any of the labels.)

Power Supply and Power Cord Use
Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to follow this
warning may cause an electric shock.
Plug into a proper power source.
Use a proper wall outlet. Use of an improper power source may cause a fire or a power
leak.
Do not install the workstation where you need an extension cord. Use of a cord that
does not meet the power specifications of your workstation may heat up the cord and
cause a fire.
Do not connect the power cord to an outlet that has an illegal number of connec-
tions.
The electric current exceeding the rated flow overheats the outlet, which may cause a
fire.
