2.3. Receiver Board AMRB 700V5.3
Picture 2.3 below shows the RX board and the relevant components:
Each RX board controls the resonance of two loops in the RX antenna. The matching for
the upper and lower receiver loop can be adjusted through the 2 rotary switchesTW1 and
TW2. TW1 adjusts the matching for the upper loop and TW2 adjusts the matching of the
lower loop.
In this case, the RX matching can be modified for the upper and lower loop using the
rotary switches TW1 and TW2.

All our antennas are pre-tuned in the factory and RX antenna matching WILL NOT
HAVE TO BE ADJUSTED in almost any case. When installing the system near
metallic frames or metallic doors, resonance value may be affected.
