Keyboard test
In the keyboard selftest dialog box, the keys can be pressed in any order. Each time a key is pressed,
there is acoustic feedback and the detected key is marked. If a key is pressed more than once a warn-
ing is output. This means that specific keys or the whole keyboard can be tested.
This dialog box can be quit only if the
[¶]
symbol appears on the right of the title bar. This symbol ap-
pears either after all keys have been pressed or when no key has been pressed for 15 seconds.

Selftest Keyboard dialog box
The first stage in testing the whole keyboard is to press all the keys in any order without checking each
response in the display. If each key has been activated once and only once, an OK message is output
and the test is over. Keys that are not activated during the test do not output a tone and afterwards do
not exhibit any marking. If a keystroke, e.g. due to a short, activates several keys, a warning message
is output during the test. You should then repeat the test, observing the response on the display inten-
sively.
