3. Verify that the tablet and pen are working:
• Press the pen tip against the display and verify that the status LED lights blue.
• If the LED does not light, verify that the DTF-521/PL-521’s USB cable is plugged into an active
USB port. If the pen display is plugged into a USB hub, try plugging it directly into the USB port
on your computer.
• Be sure that the USB port to which you are connecting the DTF-521/PL-521 has not been
disabled. It may be necessary to check your system BIOS setting to verify that you have
connected the pen display to an active USB port.
• The status LED will light blue when the DTF-521/PL-521 pen display is registered as a USB
device and the pen tip is pressed against the display.
4. Check the pen. If you cannot make a selection on the display screen with the pen:
• Test the pen by pressing the pen tip against the surface of the pen display tablet. The status
LED should light blue.
• Now, without applying pressure to the pen tip but keeping the pen within 5 mm (0.2 inch) of the
pen display tablet surface, press the side switch. The status LED should again light blue.
• If the status LED does not light blue for these tests, be sure you are using the correct pen that
came with your pen display.
If you are still having problems, you may have a defective pen or pen display.
