• Before installing the card, be sure to turn off the PC, and pull out the
power cable plug.
DANGER
Keeping power on during installation could cause electric shock.
Note
 It is recommended that you wear work gloves to protect your fingers from injuries by the
corners, etc. of the printed circuit board.
Important
 Do not install the card in an environment where static can easily be generated (on a carpet,
for example). The static charged in the human body could cause the electrical parts to fail.
Touch a grounded piece of metal to discharge the static from the body before starting
installation.
 Choose a place as free of moisture and dust as possible, and not exposed to direct sunlight.
 Observe the specified ambient temperature and humidity ranges, and do not subject the card
to condensation or other abrupt temperature change.
Note
 Do not touch other than those parts necessary for the work.
 Be careful not to loose the removed screws, and not to drop them inside the computer.
 If you find an error or failure, Contact one of Toshiba service representatives.
 Be careful not to be injured by the sharp projections on the extension board.
 In using a screwdriver for connecting the connectors or installing an extension board, be sure
to use one which fits the screws. A screwdriver that does not fit the screws is unsteady in the
cross of the screw head. Such a screwdriver will not properly convey the force, possibly
causing damage to the cross.
• Never disassemble anything other than those necessary for
installing the options mentioned in the manual.
DANGER
• Do not open the power unit cover. The high-voltage part of the
power unit could cause electric shock. The power unit is located as
shown in the figure below and carries a warning label on it for you to
observe.
