1. Before You Start...

Here are some essential precautions for handling and installing the SCSI host adapter card supplied with your
Film Scanner.

Handling Precautions

CAUTION:
• SCSI host adapter cards are precision components that are sensitive to discharges of static electricity.
They must be handled delicately to avoid damage and malfunctions. Before touching a card, dis-
charge any static charges in your body by first touching something else that is grounded, such as a
metal surface on your computer case.
• Don't remove the SCSI host adapter card from its protective wrapping until you are ready to install it. If
you must set the SCSI host adapter card down for a short period of time, place it on top of or inside the
protective wrapping.
• Never touch the terminals or circuitry on the SCSI host adapter card with your fingers. Hold the card by
its edges.
• Operating your computer with an improperly installed SCSI host adapter card can cause damage to
the card. Do not operate the computer until you have ensured that the card is installed strictly in
accordance with the instructions that follow.
• If the SCSI host adapter card does not operate correctly after following the proper installation proce-
dures, contact the retail outlet from which you purchased your Film Scanner.

About the Jumper Switches

Two jumper switches (J1 and J2) are installed on the SCSI host adapter card. Windows 95 users have no need to
change these switch settings.
CAUTION:
• The J1 jumper switch is provided for computers lacking Plug and Play capabilities. The J1 jumper
switch enables the I/O port address setting to be changed. On the open setting (factory setting), the I/
O port address is [140]. The address for the closed setting is [340].
• Do not change the J2 jumper switch setting. The SCSI host adapter card will not function if this jumper
switch setting is altered. The factory setting is closed.
