Hi, in the manual from http://www.cortechsolutions.com/getmedia/ded3f9ec-2526-4783-8b0a-da5a330faf1b/Operating-ActiveTwo.aspx, it suggests to soak the electrodes in salt water once a week or before each use. (“Soak in salt water once a week or before each use for up to 5 minutes at a time.”)

... Recently, we added an additional lab, and the technician who came out to help install it recommended that we regularly (every two weeks or so) soak our electrode braids for five minutes or so in a salt water bath.

BioSemi does does NOT recommend to soak the electrodes in salt water at all, unless there are specific problems with a set.

In case of polluted electrodes (increased low ...

... be cleaned with warm or hot water. If necessary, you can use some shampoo. The caps are not really sensitive for cleaning materials. Just let them soak in warm water, this will make the cleaning process easier/faster.

Electrodes can be rinsed with tap water without any risk. As long as the ...

Noise should be below 10-20 uV peak-to-peak (0.1 - 100 Hz bandwidth).

- the pellets have to soak for 5-10 minutes before noise and offsets have stabilized to low values.
- use a sufficient amount of salt in the water (without salt, higher noise levels may be encountered), ras a rule of the thump ...

... we have to send them away with no recording. Recently, we bought a second set of ground electrodes but we are now having the same problems with these. Can you advise about skin prep? Can you advise about cleaning? Should we routinely soak them in salt water even if they are new? Thoughts appreciated.
