DCC CONTROL

Train-o-Rama 49 ESU Install

To install your sound decoder in the 49 you will have to start by removing the shell, there are number of lugs retaining the shell using a jewellers screwdriver lift one corner of the shell and lever up each lug till it is free, once you have run around the premier of the shell it should look like the photo of the red 49, simply lift up the body shell and place to one side, we will have to remove the crew for modification if they are to be reinstalled.

Remove the DC adaptor and next identify the speakers wires, these are the red and black wires attached to the first two lugs marked "spk" on the board, remove these from the board and de solder from the speaker, you can also just coil up on the existing speaker and tape down as we will NOT be using this speaker.

Note lug positions on shell and walkway

 Next locate the speaker wires from the decoder to the speaker and trim and solder to the speaker tab on the factory board.

Pass the two wires thru the 1.0 mm hole in the speaker, seal the speaker into the enclosure using Liquid PVC or PVA. Locate the wire with the two pin plug, bare the wires, tin and solder to the speaker now mark the plug with the felt pen for the wire attached to the speaker with the black dot.

Apply a bead of thickened super glue around inside rim of the speaker and fix as shown, then apply a bead of liquid PVD or PVA to the opening to fir the black lug on the speaker.
