Note:
When making movements with several
fingers, you should avoid having them
exactly one upon the other, otherwise
this can cause malfunctions. If both fin-
gers are slightly offset diagonally or are
next to each other, movements with two
fingers will then be detected reliably.
Capacitive displays can only be used
with your fingers or an electroconducti-
ve pen. Operation with gloves, finger-
nails or a plastic stylus, for example, is
not possible.
