The diagrams below suggest how the steam and diesel soundcards can be installed with the Revolution 57000 radio control system.

The adaptor plug for custom installations is used with the outer red, orange, grey and black wires being connected as shown. The whistle and despatch functions should be set to momentary by selecting MENU ASSIGN FUNCTIONS AUX FUNC SETUP.

Note that volume is adjusted by the remote control and not by the transmitter 7, 8 and 9 buttons

Note also that early Revolution receivers, without the onboard sound, will start the soundcard immediately when power is switched on. However this will not happen with later Revolution receivers with the onboard sound. With the later ones you will need to throttle up three button presses to switch on the sound which will then stay on.
