Installation, Relocation, Storage, and Connection
TRANSFER AND DISPOSAL
IMPORTANT: About data on the hard disk
Be sure to take appropriate measures not to leak important data (e.g., customers' information or
companies' management information) on the removed hard disk to any third parties.
Data seems to be erased when you empty "Recycle Bin" of Windows or execute the "format"
command of the operating system. However, the actual data remains written on the hard disk.
Data not erased completely may be restored by special software and used for unexpected
purposes.
It is strongly recommended that the software or service (both available at stores) for data
erasure should be used in order to avoid the trouble explained above. For details on data
erasure, ask your sales representative.
❏ TRANSFER TO THIRD PARTY
Make sure to provide all the documents that are supplied with this workstation to a third party.
❏ DISPOSAL AND CONSUMABLES
Dispose the workstation, all the internal
devices, floppy disks, and CD-ROMs
a c c o r d i n g t o a l l n a t i o n a l l a w s a n d
regulations.

Warning label
❏ Cleaning of Equipmentgle
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.
Do not pull the cable when disconnecting it.
When disconnecting the cable from the device, hold the cable connector and pull it
straight out. Pulling the cable out by the cable portion or giving mechanical stress to the
connector could damage the cables and connectors to result in an electrical shock haz-
ard or a fire.
Insert the power plug into the outlet as far as it goes.
Heat generation resulting from a halfway inserted power plug (imperfect contact) may
cause a fire. Heat will also be generated if condensation is formed on dusty blades of
the halfway inserted plug, increasing the possibility of fire.
Use the authorized power cord only.
Use only the power cord that comes with your workstation. Use of an unauthorized
power cord may cause a fire when the electric current exceeds the rated flow.
Also, observe the following to prevent an electric shock or fire caused by a damaged
cord.
