! All error indications flash (1 Hz), and the corresponding helptext is shown.
If the error is an input loop error, the display backlight flashes as well - this is
acknowledged (stopped) by pushing the OK button.
* Error is acknowledged by either stepping through the basic setup, or by
resetting the device power.
Some types of errors can only be acknowledged by resetting the device power.
** Error is acknowledged by stepping through the basic setup.
