As Richard mentioned, the unit is preventing you from updating for your own protection. What you should probably do in a case like this is continue using the older firmware until your current batteries are depleted. Then, once you replace the old ones with a fresh set of batteries, perform the update. >>> mattison@xxxxxxxxxxxx Thursday, May 12, 2005 5:51:15 PM >>> I noticed that when I am about to update to the new beta, that if I have around 30% on my battery gauge, that I get a low battery message and the upgrade aborts. Normally the low battery error hasn't occurred yet at that level. Can somebody tell me why those levels were chosen? Seems like quite a bit of battery life thrown away. B.
