with alcohol and wipe down the base unit.
Once clean, reinsert the wires into the base unit, matching the wire colors to the circles on the base unit. Now you
can continue to use the device.
11.0 BATTERY REPLACEMENT
In order to replace the battery, remove the battery compartment cover on the back of the device by sliding the
cover into the open position. Use only high quality AA batteries.
12.0 TROUBLE SHOOTING
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 or body, then
the wetness of the sponges / hair / skin is insufficient or the tightness of the headband or strap holding the
electrodes in place may be insufficient. Make sure the headband or strap provides a snug fit. If the headband or
strap 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 a
smaller headband or to tighten the strap.
If your device beeps throughout the treatment session, or fails to beep at the end of the session, replace
the batteries.

13.0 THEORY OF OPERATION
The electronic waveform contains a 15,000Hz square wave carrier which is rectified, varying from zero to a maximum of 4
milliamperes. The first modulating signal of 15Hz provides an "ON" time of 50 milliseconds and an "OFF " time of 16.7
milliseconds. The second modulating signal of 500Hz changes the "ON" time series of 15,000Hz carrier pulses (750 pulses in
50 milliseconds) into 25 smaller bursts of 15 pulses each of the 15,000Hz carrier signal 375 pulses in the same 50 milliseconds.
The subject device is a bipolar version of a TENS device, wherein the first major burst of energy (50 milliseconds is positive
[above the zero axis], followed by a 16.7 millisecond "OFF " time, is then followed by a second major burst of energy (50
milliseconds is negative [below the axis]) followed by a 16.7 millisecond "OFF " time. Thus, the consecutive positive burst and
OFF time is followed by an equal and opposite negative burst and OFF time, balancing the direct current component to zero.
