If your device turns off before the 20 minutes are up, or when the device is set down on a table or lightly jarred or tapped,
re-insert the batteries. Sometimes the batteries will misalign with the metal receptors in the battery compartment and as a
result, the device will turn off when lightly jarred or tapped.
If the green “ON” light does not illuminate when the device is turned ON, first turn the device completely OFF by rotating
the dial clockwise until you hear a click, then try turning the device ON again. Replace the batteries with fresh ones if you
still have trouble.
If the yellow indicator lights (1-4) do not illuminate, be sure the sponges are new, clean and thoroughly wet. The hair / skin
beneath the sponge electrodes must also be sufficiently wet. People with thick hair may have more difficulty wetting the
hair enough to cause the electrodes to conduct. Some people with small heads will require a tighter headband to make the
electrodes work properly – adequate pressure is needed against the electrodes by the headband.
To test if the electrodes are working, press the two sponge electrodes together (like an “Oreo cookie”), turn the device ON (green
light flashing), and, while continuing to squeeze the sponge electrodes together, continue dialing up (counterclockwise)
until you see the yellow lights illuminate.
If the yellow lights illuminate when you test them but not when you have them in use on your head, then the wetness of the
sponges / hair / scalp is insufficient or the tightness of the headband holding the electrodes in place may be insufficient. Make
sure the headband provides a snug fit. If the headband is not pressing the electrodes firmly enough, adequate conductivity
may not occur. Press the wet electrodes firmly while the device is on and see if this causes the yellow lights to illuminate. If
they illuminate, you will need to tighten the Velcro headband.
