Re: Active EEG system

[Guest guest]

I've also got the active EEG 'trodes. I haven't had any problems so far. My concern is that when they short out they damage the box. Is there any way to check that if 'trodes are the bad kind? Perhaps a certain kind of twist or pull typically will hit the weak point? Is it safer to just get a new set? For replacement, is just one color bad, or could it be any of them? I'm starting to get worried. Is there a standard procedure, email , or call to make for this fix? Thanks!

Active EEG system

Hi Pete:I just read your post about the problems folks have been having with the actives. I,too, have/have had similar problems, but intermittently. I've practically gone nuts (and required additional NF to restore sanity!)trying to figure out wherein lies the problem. I'm using both infinity with EEG-Z and BE systems. With the infinity, is it possible that the black lead problem could cause an EEG-Z to burnout? Also, is it possible that this has been the reason my BE system doesn't work at all? The latter just gave up the ghost two weeks ago and I've been thinking the problem was with the pendant or the dongle. Finally, if there is a fix for the black lead (i.e. replacement), how do I get it. Will it cost anything?Thanks Mucho,Jeff

Jeff,

A quick test for the Pendant( & Pocket) is to check that the green

light on the dongle is mostly on and flashing off (whilst the Pendant

is switched on). If so, the Pendant and dongle are probably OK.

I don't follow the argument that "shorting out the Active Electrodes"damages the box". When the linked-ear setup is used, the reference electrodes are effectively being shorted (impedance = 0) What exactly do we have to avoid when using these electrodes? nick A <PetePixxx@...> wrote: I've also got the active EEG 'trodes.
