Secure the device to the PCI chassis with a screw.
Caution
It is important to completely screw the device front panel into the PCI slot, both for
mechanical stability and to create a solid ground connection. Improperly secured devices may affect
the accuracy of the device.
(SMC-Based Devices)
Some computer manufacturers use a securing lever made of plastic to secure
PCI devices; such a lever is unacceptable and
must
be removed. Use the screw provided in the kit
to screw down the digitizer. Otherwise, you must use a different computer chassis.

(SMC-Based Devices)
Verify that spread-spectrum clocking is enabled in the PC BIOS.
For information about how to verify this setting, refer to the PC user documentation.
Note
For SMC-based devices, spread-spectrum clocking varies the clock signal to spread the timing
clock signal over a small frequency range. Disabling spread-spectrum clocking may affect the
accuracy of device specifications.
USB Devices
