There are more sound functions in a recently purchased HO GG1 (Soundtraxx Digital Sound Decoder) than listed in the Quick Start Guide that came with the engine and fewer than in the Econami reference manuals for electric locomotives on the Soundtraxx site. I searched and was unable to find what sounds are produced by F4, F5, and F6. F4 may be raising and lowering the pantograph, per the Econami reference manual. Someone suggested that F6 is the air compressor with air release. I have no information about F5.
Most of the sounds have a default volume that I find acceptable, but F5 is too loud. Which CV controls the volume of the F5 sound? The CV table leads me to guess that its either 131, described as exhaust volume control, or 134, blower volume.
