Well, I got the message to wait until down to 90% and yesterday the battery was calibrated successfully. Now I was pleased to receive that questionnaire from Dean today and hope all of us will give him the answers he needs.
I'm interested though in the longer term also, in how many hours we get from a charge and, more specifically, when the battery needs to be replaced. From reading the manual, it appears to be that calibration isn't necessary until the battery begins to age, so I just wonder what we're saying here. . . .. Anyway, I'll be watching the space with interest and also hope I won't have to send ours back! -- Carol [EMAIL PROTECTED] -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Henrichsen Sent: Wednesday, August 17, 2005 12:18 AM To: Braillenote List Subject: RE: [Braillenote] problem calibrating the battery Hi, Caro. I got calibration to start by making sure the bn was lower than 90 percent before I started. I do hear battery low a number of times, but don't think I have ever heard battery critical I will have to watch for that next time. In both cases, I got calibration to start; once at 90 and once at 53. I wonder if there is a problem if you are charging then in the midst of that decide to calibrate the battery? I wonder if you need to unplug the adapter and plug it in again and then start calibration. It could be something like that. On my first attempt, I did drop the bn to 90 playing on the web then immediately plugged in the adapter and started the calibration process. That's when I got the rapid clicking sound when the talking died. It continued that all night and in the morning was still at 11 percent. I charged it to 53 percent then without unplugging, started the calibration. I wonder if that caused it to reset that time? Now that at least three of us have the problem, I don't feel so bad. I don't really want to spend 60 dollars to send my bn in when I have only had it for a month if I don't have to<grin>.
