17bii Battery Change Message #1 Posted by Brian H. (Houston) on 28 Aug 2008, 3:06 p.m. So, it's time to change the batteries in my 17bii again, but I've reprogrammed more fantastic equations that I don't want to lose (like what happened to me the last time I changed the batteries). Does anyone know of a way to change the batteries in a 17bii without losing what you've stored in memory? I looked for this topic in old threads, but didn't see where it had been discussed before. Thanks in advance, Brian

Re: 17bii Battery Change Message #3 Posted by Martin Pinckney on 28 Aug 2008, 10:06 p.m., in response to message #2 by Peter A. Gebhardt Is memory loss normal with this particular model? I don't have this problem changing batteries on my Pioneers.

Re: 17bii Battery Change Message #4 Posted by Peter A. Gebhardt on 29 Aug 2008, 6:16 a.m., in response to message #3 by Martin Pinckney Martin, I've lost my elaborated equations two times before. To not get fooled a third time, I've used the described way and had no problems. Although all pioneers "backup" the calculators memory by some sort of capacitor (as I learned later on, when bringing my problem to the attention of other forum members), I also wondered why especially my 17bII+ had these problems. s/n: CNA42903649 Best regards Peter A.

Re: 17bii Battery Change Message #6 Posted by MikeO on 29 Aug 2008, 2:49 a.m., in response to message #1 by Brian H. (Houston) Have the new batteries out and ready to insert. I put the case in my hand, then slip the calculator face down into it, about 3/4 of the way in. I found that using a paperclip to remove the batteries works well: slide on end alongside the battery stack and gently pull out with slight pressure on the side. Then slip the new batteries in immediately. Hope this helps. MikeO
