If it was me, I would stick with Power level 9, which is the default. That seems to have the most effect on average from Bob’s studies and people’s self reports. So in other words, try Omni 8, power 9, which is the default setting when you open the M1 out of the box for the first time. You can literally flip the switch on after putting in the battery and just left it pass through the three screens (which are set to Omni 8 power 9 so you don’t need to press anything), about 1 sec each and so in 3 seconds it will start pulsing (you’ll here it clicking which means it is working).
There are tons of posts about the common human belief “more power is better” is not the case with inductive PEMF. Dr. Bob Dennis’ technology is incredibly more efficient than traditional non inductive PEMF and more power appears to on average not be better.
The neat thing in my opinion about Dr. Bob’s technology, is I don’t have to worry “oh, if I get the wrong power level or protocol, it won’t work at all.” Basically Omni 8, Alpha, and Schumann 4 with power 9 seem to work well for most people, so the biggest variable we should focus on is the # of hours we are using it, and making sure we are getting good sleep so our body can do the repairing that to the extent that it can.
In summary, the biggest variable you can control for is the # of hours she is wearing it. If it was me, I would wear it 24x7. I bought extra batteries and always have a snack bag of charged batteries on me. I swap in a new battery about 3 hours, even though it could go 6-8. That way I am truly at “power 9” versus a much lower power due to a drained but still functioning battery.
