I just thought of something:
Maybe the SP LPFv2 switch cuts out 'everything' including the power and the signal when it is in the 'OFF' position. (Because in SPv2, they moved the setup button to where the switch is, so there must be a micro circuit on the switch itself)
Since option 2 works for you, then don't worry about it. Just go out and have fun!
