The durable, self-contained Piezo-DX produces a short wave pulse of 12 microseconds with peak voltage of approximately 5,000 volts. The pulse is generated when pressure is applied and released to the tuned solid state ceramic quartz crystal in the unit, creating a tiny electrical charge. No batteries required. The output is not adjustable. Size: 4.8" x 0.6" dia pencil like shape. Weighs 37 grams (1.3 oz).
How to Use: Apply perpendicular to the body, press button with thumb until a click is heard, then release thumb. Do not activate one point more than a few times. Do not activate in an open-circuit mode (i.e. tip not contacting body), otherwise output will weaken prematurely. Depending on frequency of use, intensity will slowly diminish over time.
Contraindications: Do not use on patients with cardiac pacemakers of any type; over the carotid sinus area; on the face near or around the eyes; transcerebrally or transthoracically; on children or pregnant women; over or near skin cuts, infections, or known or suspected malignancy; on patients who have implants of any electrical nature; or on patients with cardiac disease. Do not use around oxygen or other flammable materials.
