Radiated power
Using the "Settings - Read points" menu item of the WBM, you can set the radiated power.
Select the radiated power so that the required transponders can be identified reliably but
without overreach. In this case, the following applies: "as much as necessary, as little as
possible".
In the "Settings - Activation power" menu item, you can find the optimum radiated power for
reliable transponder access.
