Hello, We bought all new sets of electrodes a few month ago, and they were working fine for a while (one experiment per week or so). But since a few weeks ago, we have got the same problem that blue light starts to keep blinking and we couldn't collect any data... As the electrodes are pretty new, w...

Thank you very much for your very quick help! We checked all the electrodes and found that two of EX electrodes cause the blue light blinking. Now, it makes complete sense because we only bought new A,B,C,D and CMS/DRL electrodes, and kept using old EX1-8 electrodes. We really appreciate for this an...

We had exactly the same trouble with the following post, and we bought a new set of electrodes (A,B,C, and D) a few month ago. But yesterday, the same trouble happened. The Blue lights (for CMS/DRL electrodes) on the AD-box was blinking and we couldn't collect EEG data. So we tried a salt-water buck...

Thank you very much for your kind help.

We tried one-bucket test, and we did confirm that B1 electrode cause the problem. Although C1 electrode seemed to be fine during the test, it might be better to ask to fix it too, as we bought these electrodes almost two and a half years ago.

We have been having a problem in our lab with the offsets exceed +262 mV and CMS/DRL light blinking. When the ERP starts, all the electrodes are fine, and measuring in an appropriate range. We first incountered the problem when trying to correct the C1 pin electrode offset. After pulling out C1 and ...
