To leave on or not to leave on, that is the question...
OK, so I have an HFS-5, and, to be completely honest, I don't go through too much juice on a day to day basis. In fact, there are some days that I probably don't even make it into spray.
So here's my question- should I just turn the DDS3 off until I'm ready to use it? Is there a real difference in component life leaving it on vs. turning if off when I don't think I'll be using it?
And one last question - for those who have the DDS3, does your idle go up when you turn off the unit? Mine jumps to about 12-1300 RPM when I disengage it.

does it stay at 1200rpm? or does it jump up then come back down?

No, it stays at the faster idle when the WI is off.

My idle does not change with unit on or off.
