(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.

Replace the PC cover.

Plug in and power on the PC.

(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
To install a USB device, connect the USB cable to the PC and the digitizer, as shown in Figure 6.
