Battery Indicator Shows Discharged after Firmware Update


After performing a firmware update, the battery indicator on the screen shows discharged, even if the battery was completely charged before performing the update.


This is a usual behavior of the FSH models after a firmware update. The firmware update procedure overwrites the battery indicator's memory. The battery indicator shows discharged.

To recover, connect the FSH via a power adapter to the main power line. Switch the instrument off. After a short time (several minutes) the battery indicator is refreshed.
