| It is used to power the mobile using an USB source instead of the box with obviously the power timing controlled by the box.
In this mode the box is safe in case of any wrong operation with the fbus cables (expecially UFC) or if the mobile is faulty.
It has as well a selector to correct the BSI value on the cables adding values 0 (no correction), 2.1, 3.3, 5.1 or 10 Kohm.
