M3SR Series 4100 Control Unit MTC 4/4 (4004)
When at low temperatures (below 10 °C) the display
background illumination is frequently switched on and
off, the durability of the illumination decreases consid-
erably. For operation at low temperatures we therefore
recommend 15 minutes as the shortest time for
screen saver activation.
At temperatures around or below the freezing point the
screen saver should not be used at all (setting OFF), so
that the control unit is constantly kept warm by the back-
ground illumination.
