The switching between antenna loops minimizes the size of detection holes at the null points of
the RF field.

Table 1 explains each of the jumpers on the TR4022 board and 4.0 explains the switches on the
TR4022 board that must be configured before the system will operate.  The illustrations on the
next pages shows the position of the jumpers, switches, and potentiometers on the TR4022 board
used during configuration.  The top of the shield is held with 4 thumb turn screws. With the top of
the shield removed all the switches can be set without removing the electronics from the antenna.

If for some reason the circuit board needs to be removed from the antenna housing, remove the
three mounting screws from the backside of the board housing.  Removing the rear cover of the
antenna assembly can access them.  Before completely removing the electronics package from the
antenna loosen the screw near the TX1 and TX2 antenna connector and remove the spade lug.
MAKE SURE WHEN REINSTALLING THE ELECTRONICS PACKAGE THAT THE SPADE
LUG FROM THE SHORTED TURN IS REINSTALLED IN THE SAME PLACE.
