6 Replacing batteries
If an empty battery is displayed via the app or the
device (see „7.4 Error codes and flashing sequences“
on page 39), replace the used batteries by two new
LR03/micro/AAA batteries. You must observe the correct
battery polarity.
To replace the batteries of the temperature and humidity
sensor, please proceed as follows:
• Once mounted, the sensor can easily be pulled
out of the frame (A) or removed from the mount-
ing plate (E). To remove the sensor (B) from the
frame, take hold of the sides of the sensor and pull
it out (see figure 2). You do not need to open the
device.
• Turn the sensor over to remove the batteries.
• Insert two new 1.5 V LR03/micro/batteries into
the battery compartment, making sure that you
insert them the right way round (see figure 7).
• Put the sensor back into the frame. Make sure
that the clips on the mounting plate latch into the
openings on the sensor.
• Please pay attention to the flashing signals of the
device LED while inserting the batteries (see „7.4
Error codes and flashing sequences“ on page
39).
