When You finish working with Data Logger TERMIO 25, You can switch the device off by

12. Battery replacement
A shape of battery on TERMIO-15 display signalizes the user that they should replace the
battery. While using the battery, the device is working: it measures the temperature, it saves
it to its memory and it displays exceeded temperature values.
A bigger shape of the battery on the screen alarms that each of device's function were stopped
and TERMIO-15 cannot work any longer. Replace the battery to continue working with the
Datalogger.
What we know from experience is that the battery should be replaced every year if one use
the device rarely.
