The alarm speaker button is only illuminated when there is an internal alarm. When an alarm occurs,
the alarm speaker button will flash in an uninterrupted sequence, and the speaker will beep in an
uninterrupted sequence.

active
The alarm speaker can be muted via the alarm speaker button.
When the alarm (is read and) acknowledged on the AlphaPilot MFM control unit, then the
illumination will be constant, and the speaker will be muted (if not muted already via the FU Tiller).
When the alarm is accepted (e.g. problem solved), then the illumination on the alarm speaker button
will turn off.
Dimming
Buttons DIM - and DIM + are always illuminated (dimmed to a pre-set brightness level) and control is
always allowed.
Push the button DIM - or DIM + to simultaneously adjust the brightness level of all indicators on the
FU Tiller and interconnected modules.
