How to tune the transceiver antenna
This section explains the proper way to tune the ARGUS AM Floor System transceiver
antenna.
1. Make sure the transceiver antenna is placed in the required position, following the
instructions as described in chapter 7.
2. By factory default, all tuning jumpers are placed on the electronic board.
3. The Jumper settings section of the Tuning screen shows the tuning quality of TRx1
and TRx2 coils as well as instructions on which jumpers to remove and/or to add,
see Figure 52.

4. Remove the jumpers from Tune 3 and start tuning the “in phase” (orange line).
5. Follow the instructions given by removing jumpers from Tune 1 and Tune 2. The
higher numbers represent a higher capacitance (large steps), the lower numbers
represent a lower capacitance (small steps).
6. After removing the first jumpers, the tuning signals should become visible, like in
Figure 53, but the tuning is (most likely) not optimal yet.
7. Keep following the instructions on the screen until you have reached the optimal
tuning as close as possible to 100%, like in Figure 54, where the tuning quality of
TRx1 is 98% and TRx2 is 95% and no more instructions on removing or adding
jumpers are given.
