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 DTU-1931's USB cable is plugged into an active
USB port. If the DTU-1931 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 has not been disabled. It may be
necessary to check your system BIOS setting to verify that you have connected the
DTU-1931 to an active USB port.
•
The status LED will light blue when the DTU-1931 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 or eraser (when equipped) against the surface of the
pen display tablet. The tablet 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 (when equipped). 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 DTU-1931.
•
See Testing your pen on page 30 for detailed information.
If you are still having problems, you may have a defective pen or pen display.
