Press 1(Yes) to replace the receiving calculator’s existing data with the new data, or 6(No) 
to skip to next data item.
No: Overwrite check is not performed. If the receiving calculator already contains the same 
type of data, the existing data is overwritten with the new data.
k Data Communication Precautions
  Note the following precautions whenever you perform data communication.
  • An error occurs whenever you try to send data to a receiving calculator that is not yet 
standing by to receive data. When this happens, press J to clear the error and try again, 
after setting up the receiving calculator to receive data.
  • An error occurs whenever the receiving calculator does not receive any data approximately 
six minutes after it is set up to receive data. When this happens, press J to clear the error.
  • An error occurs during data communication if the cable becomes disconnected, if the 
parameters of the two calculators do not match, or if any other communication problem 
occurs. When this happens, press J to clear the error, then correct the problem before 
trying data communication again. If data communication is interrupted by the J key 
operation or an error, any data successfully received up to the interruption will be in the 
memory of the receiving calculator.
  • An error occurs if the receiving calculator memory becomes full during data communication. 
When this happens, press J to clear the error and delete unneeded data from the 
receiving calculator to make room for the new data, and then try again. 
• When sending data from the 
fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU to an older 
model calculator, folders in storage memory are not sent. In this case, send individual files 
(not folders).
k Exchanging Data with another Model Calculator
 Though it is possible to exchange data between this calculator (fx-CG10/fx-CG20/fx-CG20 
AU/fx-CG50/fx-CG50 AU) and the other CASIO calculator models listed under “To connect 
two calculators” (page 13-10), there are certain restrictions that apply when exchanging data 
with an older model calculator. 
u Transferring Data from this Calculator to an Older Calculator Model
Basically, only data for functions that are available on both this calculator (fx-CG10/fx-CG20/
fx-CG20 AU/fx-CG50/fx-CG50 AU) and the older model can be transferred. 
Data for a function that is available on this calculator but not on the older model cannot be 
transferred. Transferring Graph mode graph expression data (Y=DATA) from this calculator to 
the fx-9860G 
II , for example, will cause color information to be dropped automatically, because 
the fx-9860G II  does not support color.
