WestoneHearing Aid Saver - Large Size

I was not given insrtructions for my Hearing aid saver. I know I can put them in the microwave but for how long?

Do you have to remove your hearing aide batteries before putting them in the container?

What are the dimensions of the outer container?

what side do I put up in the microwave. I lost my insructions on the aid saver. I know you put it in the microwave for 1 minute.
