                                          Reset delle CV ai valori di fabbrica LIGHT EFFECTS WIRING Controlled by F3* If your locomotive has ditch lights, or any type of accessory lights, you can solder wires to the three solder tabs on the Sounder The center tab is the common for the light effects. You would then program CV's #118 and #119 to choose the desired light effect. Both light effects are turned on and off by function 3 (F3). There is no independent selection of either light effect. If you program the effect for ditch lights, F3 turns them steady on/off, but activation of the horn function, F2, makes them blink alternately. LIGHT EFFECTS PROGRAMMING CHART FOR CV118/CV119* You would program CV #118/119 to choose the desired light effect. CV118 for ACC1 and CV119 for ACC2. For ditch lights both CV118 and CV119 must be set to 0. *Note - The light effects operate on the track output voltage supplied by your DCC system. Please contact the locomotive manufacturer as to the operational voltage of these extra lights, so you can then choose the proper current limiting resistor (1k to 3k) to add into the circuit to prevent light bulb or LED failures. Also be careful not to short the tabs with solder or wire strands causing a short circuit and damaging the MRC Sounder. These lighting functions are not designed for headlight use, only accessory type lighting.
