Kerem Ozcan Posted April 13, 2021 Report Share Posted April 13, 2021 Hello, After 1 year and 10 days, Sonnet 2 failed, which started with an early warning of battery exhaustion. I was using the disposable batteries ZeniPower. For 13 years I didn't think I would have problems with batteries. I replaced the batteries with new ones, and it gave an early battery warning and turned off the speech processor. I learned the source of the problem from another user by trying the backup cover. I have to change the battery door like this every year? The local company of this place says I can't change from warranty. I think this cover is definitely manufacturing flawed. Is there any work on Med-el cover? Quote Link to comment Share on other sites More sharing options...
