CARING FOR THE DTU-1931
Keep the pen and the DTU-1931 LCD screen surface clean. Dust and dirt particles can stick to the
pen and cause excessive wear to the display screen surface. Regular cleaning will help prolong the
life of your LCD screen surface and pen.
Keep the DTU-1931 and pen in a clean, dry place and avoid extremes in temperature.
Room temperature is best. The DTU-1931 and pen are not made to come apart. Taking apart the
product will void your warranty.
IMPORTANT: Take care to never spill liquids onto the pen display or pen. Be especially
careful of getting the display, or pen buttons and tip wet – they contain sensitive electronic
parts that will fail if liquids enter them.
CLEANING
To clean the DTU-1931 casing or the pen, use a soft, damp cloth; you can also dampen the cloth
using a very mild soap diluted with water. Do not use paint thinner, benzine, alcohol, or other
solvents to clean the unit casing or pen.
To clean the display screen, use an anti-static cloth or a slightly damp cloth. When cleaning, apply
only a light amount of pressure to the display screen and do not make the surface wet. Do not use
detergent to clean the display screen; this may damage the coating on the screen. Please note that
damage of this kind is not covered by the manufacturer's warranty.
REPLACING THE PEN TIP
The pen tip (nib) will wear with normal use. Excessive pressure will cause it to wear sooner. A worn
nib may damage the coating on the DTU-1931 display screen. To avoid this, periodic tip
replacement is recommended.
When the nib gets too short or develops a sharp edge, you can replace it with one of the extra nibs
that came with the pen.
To remove the old nib:
Clasp it with a Wacom nib removal tool,
pair of tweezers, needle-nosed pliers, or
similar instrument and pull the old nib
straight out of the pen.
Replace the pen nib when it gets too short –
less than 1 mm (0.04 inch).
W
ARNING
Prevent children from swallowing the pen nib or side switch. The pen nib or side switch may accidentally
be pulled out if children are biting on them.
IMPORTANT: When not in use, place the pen in the pen storage compartment, or lay it flat
on your desk. To maintain the sensitivity of your pen, do not store the tool in a container
where it will rest on its tip.
APPENDIX
To insert a new nib:
Slide it straight into the barrel of the pen.
Firmly push the nib until it stops. The new
nib will slide into the correct position.
