Tuning
The NEXUS AM Deactivator is performing at its best when maximum power is being
transmitted at 58kHz. The Tuning screen shows a graphical display of the antenna loop
tuning and its associated power.

Figure 16: Tuning
The highest voltage output should be at 58kHz (the vertical red line). The spot where the
orange curve crosses the red line is the actual transmitted power, also indicated in the
white box on the left. A higher output will increase the performance of the deactivator,
where a lower output will result in less performance.

The tuning is fixed and cannot be changed. The graph only indicates the antenna voltage,
so you can determine if it is reduced when the deactivator is placed in an environment
which contains metal objects.
so you can determine if it is reduced when the deactivator is placed in an environment
which contains metal objects.
If the deactivator is positioned close to metal surfaces, the antenna voltage will drop.
When the antenna voltage drops below 47V, a problem will be raised that the antenna is
detuned. Since reduced antenna voltage results in less performance, it is strongly
recommended to ensure that there is enough distance between the deactivator and metal
surfaces and objects (see section 2.2.1).
