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 labels are typically empty (a wait note is an exception to this.)

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 | 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 | |
