Troubleshooting
This guide contains possible issues and their solutions using the X-trodes ARK V1.3.
LED indicators
I cannot insert the SD card properly.
I turned on the DAU, but the LED flashed red instead of solid green.
My DAU is not displayed on the main screen to pair it, although the LED is green.
I have a DAU that cannot pair to a specific tablet
I turned on the DAU, and the LED is solid green, but the app continues to scan for devices.

Electrode patch
I don’t see proper electrophysiological signals in some of the channels.
Charging
I connected the DAU to the app but could not find the battery status.
When I am charging the DAU, the LED is light orange, but the battery status in the app is full. Do I need to wait until the LED is green?
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.
