8. Replacing the pen tip
The pen tip (nib) can wear with normal use. In the unlikely case that the nib gets too short or develops a
sharp edge, you can replace it with spare nibs.
WARNING
Prevent children from swallowing the pen tip.
The pen tip (nib) may accidentally be pulled out if children
are biting on them.
In the unlikely case a nib becomes angular due to wear off, it may damage the coating on the STU-520A
display screen. To avoid any damage, nib replacement is recommended in this case.
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.
