Production / After Sales Interface

Test pads are placed on engine PWB bottom side for service and production trouble
shooting purposes.
The standard 5 pin test pattern is shown in figure below. NSB-9 has two pins for FM-
radio testing. The pins are connected in parallel with two system connector audio output
lines (HSEAR P and HSEAR R N). The FM radio can be tested between those lines.
