Hopefully it's not the condenser. It's one of Jon G's.
I wonder if the Advance/Auto Zone people can load test a 6v battery?
You just hit the little microphone icon when the keyboard comes up to type. If it didn't have that, I would never send a text message or type a response on this forum from my phone. I'm like the least technologically advanced member of my circle of friends and discovered it by accident. Some of them didn't even know their phone could do that.
