larity.
To replace the device batteries, please
proceed as follows:

• Remove the used batteries.
• Place the two new 1.5 V LR6/Mi-
gnon/AA batteries in the battery
compartment (F) in accordance
with the polarity markings.
• After inserting the batteries, pay
attention to the flashing sequen-
ces of the LED
and flashing sequences" on page
23).
• Put the cover (B) back onto the
mounted electronics unit (D), en-
suring that it latches fully into
place.
Once the batteries have been inserted,
the device will perform a self-test for
approx. 2 seconds. Afterwards, ini-
tialisation is carried out. The LED test
display will indicate that initialisation
is complete by lighting up orange and
green.
