k Optimizing the Storage Memory or SD Card Memory
Storage memory or SD card memory can become fragmented after many store and load
operations. Fragmentation can cause blocks of memory to become unavailable for data
storage. Because of this, you should periodically perform the storage memory or SD card
optimization procedure, which rearranges the data in the storage memory or SD card and
makes memory usage more economical.
u To optimize the storage memory
1. On the initial MEMORY mode screen press
5(OPT) to optimize the storage memory.
2. Select the memory you want to optimize (fx-9860G
SD only).
• b ... storage memory
• c ... SD card
3. Press b or c to start optimization.
The message "Complete!" appears when the optimize operation is complete.
Press J to return to the initial MEMORY mode screen.
# In some cases, the amount of free memory
capacity may be unchanged when you check
it after performing the optimization procedure.
This does not indicate any problem with the
calculator.
