4.

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.

5.

Replace the PC cover.

6.

Plug in and power on the PC.

7.

(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 5.
