Info
Each axis (X,Y, and Z) of the LF antenna can be
tuned exactly to 125kHz. The resonance
frequency of each channel can be read out via the
GUI.
The number of false wake-ups can be read out
and displayed via the RSSI-LEDs.
Pressing FALSE WAKEUP twice in quick
succession resets the number of false wake-ups.
Each RSSI-LED lights up shortly.
