Hello,
I have a weird problem in my FSH3, the internal battery went bad and when th FSH3 was without any power, all the installed options are gone! I tried to entrer them again but when there is ´battery or external power, the options are cleared! Could be some EEPROM which went bad? the cal values seems to be ok, it is only the options which disappeared.

The same issue. I guess the options on FSH3 in the CMOS))
Guys, you know, this so stupid.
The solution with CMOS is generally not very good and this can be justified for devices of the 80-90s, but at least lithium batteries were used there and had a service life of 20 years or more.
The self-discharge of the NIMN battery is about a year, and several months when it is inserted into the device and powers some kind of logic.
You haven't used it for several months - your options are gone and it's good if you have a sticker with a code)))
You decided to carry out repair - the options are gone.
Cool)
