ELECTRICAL SPECIFICATIONS
• Maximum <1.5mA Peak ~40 Volts Peak-Peak into typical 4k ohm load.
Minimum <~10 microamperes, 10 Volt Peak-Peak at lowest setting.
Output impedance ~20k ohm.
• Modified rectilinear wave with rapid rise time (under 1uS). There are over
500 harmonic frequencies delivered in each pulse as observed on a
frequency domain (not time domain) spectrum analyzer.
• 1,000 Hz Squarewave (+/- 1%) pulse-modulated by 111.11 Hz (+/- 1%)
Squarewave. Waveforms are Quartz Crystal-Controlled for precise
frequency output.
• Pulses are Bi-Phasic (AC) with no direct current (DC) or offset bias.
Output is transformer coupled so that no DC can appear at electrodes.
The algebraic sum of positive and negative-going pulses is zero.
One 9-Volt Alkaline battery.
Note: An Alkaline battery must be used for the unit to work properly.

TROUBLE SHOOTING
If the green mode light does not come on
, replace the 9-Volt Alkaline
battery and turn the unit ON. If the problem persists, first check to be sure the
battery has been placed correctly. For repair information, see page 12.
If the yellow light does not come on
when the earclip electrodes are
touched together, check as follows:
1. Ensure the conductive rubber electrodes are clean:
a. Remove the earclips from the cord.
b. Pull the rubber electrodes out of the earclips and clean with a soft cloth
and toothpick or similar object.
c. Place back into earclips.
d. Ensure the pin on the cord is fully inserted into the earclip.
2. Plug the earclip cord into the unit.
3. Turn the unit ON to maximum intensity and touch the electrodes together.
The yellow light should come on.
If the yellow light still does not come on, see page 12 for repair information.
SUMMARY OF LIGHTS:
GREEN lights: Indicate which mode is selected.
RED light: Indicates the battery is low and will soon need replacing.
YELLOW light: Indicates current is flowing.
CAUTIONS
Do not use in the following situations as safety has not been explored
:
•
In the case of pregnancy, nursing or trying to get pregnant.
•
With a pacemaker or other active implanted device.
•
With seizures or psychotic conditions.
