6.4 Reset to factory default
If the module seems to function weird this could usually is caused by unintended settings. In this case
a reset to factory default might be useful. To do this switch off the module and short-circuit pin 1 and
pin 3 of the free contacts for a 6-pin connector on the backside of the module. See Figure 6.3. Turn on
the module and switch it off again to remove the short-circuit. All settings are now at factory default.
