Updating the Calculator Operating System
Important!
• Updating deletes all data in the calculator’s Main Memory. If you need the data, make sure you back it
up before updating. Use the Memory app backup function to backup data.
• If you have multiple calculators to update, do so one at a time. Be sure to connect only one calculator to
the computer at a time. Connecting multiple calculators to your computer and executing the OS update
operation creates the risk of data being deleted and damage to the calculators.
• Make sure there is no other CASIO device besides the calculator whose OS you are about to update
connected to the computer. If there is, disconnect the other device.
• Do not perform any of the following operations while OS Update is running.
– Connecting a USB device to the computer
– Turning a connected USB device on or off
– Starting up another application on the computer
– Inserting a memory card into the computer or removing a memory card from the computer
