Activadose tDCS Device User Manual
Preparing Electrodes and User for tDCS Session
A. Examine the skin sites for both electrodes. The skin must be free of damage, i.e., avoid
broken skin, skin with ingrown hairs, acne, razor nicks, wounds that have not healed,
recent scar tissue, etc.
B. Apply 0.9% saline to sponge electrodes according to instructions found in the "Saline
application" section.
C. Remove any jewelry that may come in contact with either electrode.
D. Attach the twin lead connectors to the electrodes. Refer to specific electrode montage of
interest for specific guidelines concerning polarity.
a. Note: Red Anode ( + ) Black Cathode ( - )
E. Apply tDCS sponge electrodes to user at the intended positions according to the specific
electrode montage selected using the Caputron Universal Strap.
Operating the Activadose II tDCS Unit
Normally, a typical tDCS session requires only three steps:
1. Select Dose (Timer for tDCS)
2. Set Current
3. Start tDCS session.
A. Select Dose: Depress the ON / DOSE / START knob or turn clockwise to turn on the
unit. The unit performs a "System Check." The unit is preset at 40.0 mA-min (milliamps-
minutes) dose. If desired, dose can be changed.
EXAMPLE: For a 40 mA-minute dose, the display shows:
NOTES:
1.
Dose is the timer
a. 4 mA x 10 min = 40 mA-
b. 2 mA x 20 min = 40 mA-
c. 2 mA x 40 min = 80 mA-min (dose)
2. After a two-second delay, current can be set.
B. Set Current: Read electrode instructions for recommended current. Turn the CURRENT
knob clockwise to set the current. Maximum possible current is 2.0 mA or 4.0 mA.
EXAMPLE: To deliver 4.0 mA of current,
the display shows:
C. Start session: Turn on the ON / DOSE /
START knob clockwise one "click" to start
stimulation. Current automatically ramps up
gradually to desired set point and display shows:
NOTES:
1.
"DOSE" shows dose delivered
as mA-minutes accumulate.
