Activadose tDCS Device User Manual
F. After tDCS Session:
Remove electrodes: Disconnect the lead wires and remove the electrodes from the user.
Discard the sponge electrode after 3-4 uses. They should not be reused past this. They
will have non-uniform current distribution.
Electrode Placements
As tDCS is still investigational (As of October 2018), Caputron is not permitted to
provide medical use instruction on electrode placement for various electrode montages.
However we do provide a list of third party resources on our website that allows you
access to a thorough archive of current, up-to-date tDCS electrode montages with their
corresponding intended effects. *Caputron is not liable for the information provided on
these websites and the user should always refer to the actual publication for the most
up-to-date and accurate information.

Saline Application

An application of ~7 ml of 0.9% saline to the 2x2 electrode sponge insert or ~15 ml of
0.9% saline to the 3x3 electrode sponge insert is recommended for optimal stimulation
configuration. Saline application should be performed after dry electrode sponge
has been inserted into electrode holder.
Sponge and Electrode Maintenance
It is important to properly maintain sponge electrode shells and electrode sponge inserts
in order to obtain consistent and uniform current distribution throughout the tDCS
electrode, this minimizes the chance of current "hotspots" where current may tend to
concentrate at certain areas of the electrode sponge surface due to the constant wear
and subsequent degradation of the sponge material through usage—this results in
inconsistencies in current density distributions. As a result, sponges should be
discarded after 3-4 uses.
It is advised that you replace your electrode sponge inserts every 3-4 uses, and replace
your sponge electrode shells every 2 months. Make sure to position the connector
portion of the conductive carbon rubber with the bump facing away from the electrode
sponge insert—this ensures proper surface contact between the conductive rubber and
the electrode sponge.
Activadose II tDCS Unit Maintenance
Keep device clean and ensure dust does not enter battery compartment and all other
openings. Clean your Activadose II tDCS unit with a damp cloth when necessary.
