From Nikon:
Changes from Firmware Versions “A” 1.02/“B” 1.02 to Versions “A” 1.03/“B” 1.02
Fixed the following issues:
- The battery level indicator would on rare occasions flash if the camera was turned on with Clean at shutdown or Clean at startup & shutdown selected for SETUP MENU > Clean image sensor > Clean at startup/shutdown.
- Two different pictures with the same file number would on rare occasions be recorded to both memory cards if two cards were inserted with Overflow selected for SHOOTING MENU > Slot 2.
