Electrode patch
Charging
Settings
- I forgot to press SYNC after ending up the session, and I turned off the DAU
- What will happen if I press on executing an event while another event is already running (timer)?
- I have created a new study in the web app, and I cannot see it in my app.
- I cannot choose a study in the ‘Session Details’ screen. There is no option to add a study.
- I cannot see the default Y-axis range after changing back to default scaling from auto-scaling.
- I need help seeing all my montages.
Data extraction
- I can see only one SD EDF file in the processed files, and the file does not include the montage I chose.
- I am trying to download multiple EDF files with the check-box selection, but nothing is downloading when I click on the ‘download’ button.
- After renaming a session, the annotations in the EDF file are as the previous name.
- I cannot see any signals on the display screen.
- When I press on ‘Move’, nothing shows up.
- I have created a dataset with an identical session name; how can I have a distinction?
- I uploaded the data from the SD card to the cloud, but no EDF file was created.
- I cannot remove the SD card from the DAU.
