Step Buttons Action
1 Press and hold both of the marked
keys simultaneously (a rapid inter-
mittent signal sounds) until after
approximately 5 seconds a slow
intermittent signal sounds (=RE-
SET/ manual mode)
Note: When the lift motors are at
their end position (top/bottom), the
initialisation is complete. Other-
wise, follow step 2 below.
2 Raise the mattress base height
with the “Height UP” button to the
highest horizontal position until
both motors switch off automati-
cally at the highest position, and
keep the button pressed for a fur-
ther 2 seconds. When the button
is released, the intermittent sound
signal stops.
End of initialisation.
If no adjustments are possible and intermittent sound signals sound instead, this means that
the control unit has detected a fault and is locked. In this case, reset the control unit (see
Part B: Control unit – Reset » 62).
