Why can't I get a good connection with my pendants?

[Guest guest]

I've been having so many problems with my pendants. First, Ch1 is always red - I prepped well, new battery, etc (this is with two-channel designs). Changing to another pendant -- with a different " receiver " in the computer, changing electrodes (they are new) -- still Ch 1 always red. (I have two actives, in +1 and +2, two references, linked with the jumper cable, plugged into -1 and -2, and a ground in the middle hole of the pendant.

Next -- BioExplorer stayed on " Connecting... " but never " Connected. " I changed the battery again. Still, it didn't connect. So then I plugged everything in to another laptop, and now it is connecting -- hooray -- but -- Channel 1 is always red again!

(No, I can't say that I have *ever* had a consistently good connection since starting to do NF)I am using saline and EEG spray and a nice headband. My electrodes are covered with felt pads I made myself to hold the saline. Earclips are also covered in felt pads and soaked in saline. The scalp is prepped with alcohol and NuPrep.

What could be wrong?? could it be a problem with my copy of BioExplorer? Oh -- I should say that sometimes the connection is FINE and I get beautiful EEG -- but it is completely unpredictable! and now it feels like acting up. Very frustrating!

Thank you for any ideas!Liz-- Margoshes, Ph.D.New York State Licensed Psychologist
