In order to be able to cover the greatest possible distances, the preamplifier has been activated and
transmission power set to 30 dBm by default. When operating the devices directly next to one another,
the receiver might become overloaded. In this case, remove the antennas, increase the distance
between the devices and antennas or reduce transmission power using the PSI-CONF software.
