Good afternoon,
We recorded 2 subjects today and I noted some problems which make me suspect a problem of battery.
Could you confirm that this is indeed the problem?

1. 5 sequences were recorded out of 27 for subject 1 (same pattern for subject 2);
2. An unusual electrode labelling is used when viewing the signal (e.g., 1-Fp1 in place of Fp1) (same pattern for subject 2);
3. Extra trigger being sent over the EEG sequences associated to the reference that battery was low - it has however it has been fully charged before subject recording (same pattern for subject 2).

I guess it would be useful to send screen captures to illustrate all of this but this is not possible through this interface.
I am however happy to send it to you by email.
If this is indeed the problem, would it be possible to send the battery back to you for checking?

Thanks.
Adelaide

The AD-box is on speedmode 0, instead of 4-7. Or are you doing hyperscanning (2 subjects with daisy chained AD-boxes) ?

It is not a battery problem.

Thank you for this reply.
