CAUTION

Strong magnetic field

The Digitized Per Pin (DPP) Receiver Distributor (Rx Dist) has no ferrous material and will not be attracted to the magnet, but the eddy currents can cause resistance when you pull the DPP Rx Dist away from the magnet.

When removing and replacing the DPP Rx Dist, keep the receiver as far away from the magnet as possible while moving it.

Loosen four screws and remove the DPP Rx Dist.

Note: The screw holes for attaching the DPP Rx Dist are a keyhole shape or slotted so it is not necessary to remove the four screws. Just loosen them.
