Notes
·
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

Notes do not require user input, although a user can dismiss most notes by
pressing any key.
The following note types are in use:
confirmation note
information note
warning note
error note
permanent note
wait note
An information 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.)
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.
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.
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.
A note that must remain on screen for an indefinite
time. The user can't dismiss it. Example: insert SIM
card.
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
