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.

sion if the battery is not replaced
correctly. Replace only with the
same or equivalent type. Never

teries. Do not throw the batteries
into a fire. Do not expose batteries
to excessive heat. Do not
short-circuit batteries. There is a
risk of explosion
After replacing the batteries, you
