Thanks for the link! I found the problem is with the HA, not the receiver. (I wonder why they call the speaker the receiver…) The video was very helpful to take the case off the HA. I did that and left it in the food drier all night, but it still has the problem. I took off the rubber membrane that covers the mics and switches, and am trying a little more aggressive drying technique with the food dryer, but my hopes are not high.
I also found that you cannot use an M70-R with an M90-R if you want Bluetooth to both ears. The Phonak app allows you to pair with only one or the other, and looks for the pair of both the M70-R and M90-R. That is a disappointment. At this point, I have the choice of the M70-R pair I have been using or one M90-R or both M90-R, but a very annoying static. I suspect it is a microphone problem. I took off the rubber membrane that covers the mics and switches, and am trying a little more aggressive drying technique with the food dryer.
Does anyone have any other ideas?
Thanks,
Rob
