Whenever I power down my GT 97, it looses the volume and "free play" settings. Resetting them requires opening the back. Is this a storage battery issue, or am I missing something obvious?
It's either a battery issue or the static ram on the board could be bad. I had the same issue on my GT99. I replaced the battery but that didn't work so I just bought a cheap replacement board instead. The static ram is at spot U50 on the board. If you get the number off of it you could probably find one. I contact IT Technologies and the would sell one for $12 PLUS a $25 handling fee PLUS shipping.
Replacing the battery and the settings save fine. There is another thread reporting that the battery died again after a few days. I will update here if that happens.
