I came across an older Fieldfox N9912A today with firmware version A.05.53. The RTC battery appears to be dead as the date resets each restart. It seems to work fine and I'd like to update the firmware but after reading that the new firmware is picky about date changes I'm not so sure it is a good idea. The best solution is to have the RTC battery replaced but before doing that is it safe to update the firmware or will it fail to operate and complain about date issues?
I also thought about updating to A.06.24 which doesn't have the date issue but you guys seem to have removed it from the download section - is it possible to get the file?
