A note is a feedback component that informs the user about the current
situation. A note contains a text and possibly a graphical element. The softkey
labels are typically empty (a wait note is an exception to this.)

pressing any key.

The following note types are in use:
confirmation note Informs the user about a successfully completed
operation. Short duration, subtle tone. (This should
not be used after every kind of successful action;
see the guidelines below.)
information note Gives information about an unexpected situation
during usage of the device. Longer duration and
more noticeable tone than in a confirmation note.
Errors that are not too serious should cause an
information note.
warning note Used when the user must be notified about
something that may require action. Fairly long
duration, and a sound that can be heard (and
distinguished) even when not concentrating on the
phone. An example: battery low warning.
error note This is a red light. It should only be used when the
user has tried to do something that may cause a
considerable problem. See the guidelines below.
permanent note A note that must remain on screen for an indefinite
time. The user can't dismiss it. Example: insert SIM
card.
wait note A note containing a progress or wait graphic. (Wait
graphic is an animation of indefinite duration,
whereas progress graphic is a growing bar that can
be used when it is possible to estimate the duration
of the operation.) Used during operations that take
a long time. The user should be able to stop the
