"PAUSE"
BAT indicator lights
during tDCS
session.
"LOW BATTERY"
and "BAT" indicator
lights when unit is
turned on.
Possible cause
•
Loose electrical connections
at one or both electrodes.
•
One or both electrodes have
pulled away from the skin.
•
Electrode not properly
hydrated.
•
Maximum dose of 80.0 mA-
min has been reached.
•
Maximum current of 4.0 mA
has been reached (2.0 mA
for respective version).
•
Skin resistance at an
electrode site is too high for
preset current level.
•
Stimulation has been
paused by decreasing
current to 0.0 mA, or by
depressing the CURRENT
knob.
•
Battery voltage is
decreasing during
stimulation but stimulation
may continue.
•
Battery voltage is too low for
proper operation.
•
If battery voltage is very low
only BAT indicator lights.
•
Unit will not allow
stimulation to begin.
Corrective Action
•
Turn CURRENT knob
counterclockwise to
"PAUSE" stimulation and
silence beep.
•
Correct problem.
•
Turn CURRENT knob to
reset current. Restart
stimulation.
•
Refer to electrode
directions for dosage
recommendations
•
Adjust current
•
None. The unit
automatically ramps
current up to preset level,
or as high as possible, and
adjusts time to delivered
desired dose.
•
During a pause, electrodes
may be disconnected,
moved or replaced.
•
Correct situation that
caused stimulation to be
paused.
•
Turn CURENT knob to
reset current. Restart
stimulation.
•
After stimulation is
finished, replace battery.
•
Replace battery.
