TP5 consists of a vertically mounted, unmarked 0 Ohm resistor. A 10 k resistor is connected to TP5. The other lead of the 10 k resistor is connected to piece of shielded wire. The braid of this
wire can be connected to the shield of a coil close to the receiver IC.
The other side of the shielded wire is connected to a 3.5 mm jack that can be mounted in the side panel of the scanner.
