at the bottom of the screen to validate.
|

|
- Check that you are connected to the internet.
- Accept the validation message, to synchronize the tablet data with MEMO, by clicking on « OK ».
- This may take several minutes.
Note: Make sure the tablet remains connected to WiFi until the end of synchronization.
The message "synchronization complete" should appear.
Congratulations, you are now ready to use the tablet again.

- The synchronization cannot be done if:
- Wrong connection data (either wrong user code or wrong password or both)
- Disharmony between the application version installed and the MEMO version (you will then need to install the correct version of the application !)
NB : When the synchronization cannot be done, you will receive an error message
NB : When the synchronization cannot be done, the dashboard is blank
