APPENDIX
Caring for your pen display
Keep the pen and your pen display LCD screen surface clean. Dust and dirt particles can stick to the
pen and cause wear to the display screen surface. Regular cleaning will help prolong the life of your
LCD screen surface and pen. Keep the pen display and pen in a clean, dry place and avoid extremes in
temperature. Room temperature is best. The DTF-521/PL-521 and pen are not made to come apart.
Taking apart the product will void your warranty.
Cleaning
To clean the pen display 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. 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.
If the pen nib wears and becomes angular, it may damage the coating on the DTF-521/PL-521 display
screen. To avoid this, periodic nib replacement is recommended.
Important: When the pen is not in use, place it in the pen tray, 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.
To remove the old nib:
Clasp it with a pair of tweezers, needle-nosed
plier, or similar instrument and pull the old nib
straight out of the pen.
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.

ARNING
Prevent children from swallowing the pen tip or side switch. The pen tip (nib)
or side switch may accidentally be pulled out if children are biting on them.
