We’ve been using the PPM for a few days and really happy with it.
One concern is that when plugged in (in use or not) the red/blue light is flashing continuously.
The PPM does charge fully. I am using the correct USB port for charging, with the charger and the provided cable.
I have tried a few outlets around the house.
I’ve noticed a faint whistling sound coming from the charger, not sure if that could become an issue?
Could that be software related? Can I reset the PPM in some way?
