UM-23100B-U User manual ATEQ F CLASS Page 71/90 
Note: if the parameters have been modified, then current and saved parameters are 
therefore different, when the instrument begins to operate, the following message is 
displayed on the screen. 
This message is not jamming and disappears after a 
few seconds. It allows informing that a parameters 
saving can be necessary. In this case three solutions 
arises: 
SAVE PARAMETERS
1) Restore the saved (current parameters will be lost). 
2) Save the current parameters in the memory (the parameters already in the memory 
will be lost). 
3)  Nothing to do and working with the current parameters.
