DISPLAY SELFTEST
The display selftest procedure consists of lighting up all of the display segments together.
The Display test is announced by a scrolling “Display test” message.
The segments are lit for a few seconds and then switched off before exiting the selftest
procedure.

SETUP together to escape”. The LCD will then show only a colon.
As soon as one or more keys are pressed, the appropriate segments out of 88:88 corre-
sponding to the pressed keys, will light up on the screen.
