Proform 850 dialing it in closer

I don't know any one that has one of these LM-2
RMA?????
Sound good. how do i go about doing this(sending it back for testing?)

They really thing it is radio/noise interference causing me my problems and said that i may need to put a filter on it.
filter????? on.....where? Tach? Every thing else? I asked were i could get one of these filters or if it was something i made...........No response.
so i sent another one, asking if they had any more suggestions...............still nothing.
RMA is something like Return Mail Authorization.
Since they can't figure it out, ask.tell them the next logical thing is for them to check it internally.

Radio noise. Ugh - Not my area of knowledge. OK - maybe. What is on the car that could create electronic noise and/or noisy electic voltage?
Alternator,
Voltage Regulator,
Electric fuel pump.
Anything else?

As far as the radio type noise, do any of these have wires that come near or run along the wiring for the LM2 ?

There's ways to shield and minimize radio interference, and capacitors can be placed in lines to reduce noise in the lines.

I'm a little dubious because I would think the WBO2 would show noise but would still record. IIRC you said it just stops recording the WBO2 but the other channels keep working like normal. Yes?

There are some guys on this board who know a lot more about radio noise.
