* The beltpack draws power from pin 2 of the XLR. Alternatively, the
beltpack can draw power from pin 3 of the XLR. To accomplish this,
unplug the internal jumper from pins 2 and 3 of P1 and connect it to pins
1 and 2 instead. To gain access to the jumper, remove the beltpack’s pack
cover by removing the four screws.
