NOTES:
Set your source volume at one-half to three-quarter up and leave it.
Always use the volume control as a master(main) volume control. It has better
electronics, higher S/N radio and is more linear than any source unit volume
control available.
If engine noise is audible , check the ground connection on all units in the audio
system.
