Warnings The long-term of chronic electrical stimulation are unknown. Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the carotid sinus reflex. Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing. Stimulation should not be applied trans-thoracically in that the introduction of electrical current into the heart may cause cardiac arrhythmias. Stimulation should not be applied transthoracically. Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, e.g. phlebitis, thrombophlebitis, varicose veins, etc. Stimulation should not be applied over, or in proximity to, cancerous lesions. Stimulation should not be applied trans-cerebrally (across the head). EMS devices should be used only under the continued supervision of a physician. Precautions/adverse Reactions Safety of powered muscle stimulators for use during pregnancy has not been established. Caution should be used for patients with suspected or diagnosed heart problems.

ATTACHING THE LEAD WIRES
-4-
The lead wires provided with the device insert into the jack sockets located on rear of the unit. Holding the insulated portion of the connector, push the plug end of the wire into one of the jacks. After connecting the wires to the stimulator, attach each wire to an electrode. Lead wires provided with the device are compliant with mandatory compliance standards set for the by FDA. Note: Use carefully when you plug and unplug the wires. Pulling on the lead wire instead of its insulated connector may cause wire breakage. Caution: Never insert the plug of the lead wire into an AC power supply socket. ELECTRODE SELECTION AND CARE Your physician/practitioner should decide which type of electrode is best for your condition. Follow application procedures outlined in electrode packaging to maintain stimulation and prevent skin irritation. The electrode packaging will provide instruction for care, maintenance and proper storage of your electrodes. Be sure to use the electrodes provided by the manufacturer and/or the similar FDA legally marketed electrode in particular the same cross section area. TIPS FOR SKIN CARE Good skin care is important for comfortable use of your device. z Always clean the electrode site with mild soap and water solution, rinse well, and blot dry thoroughly prior to any electrode application. z Any excess hair should be clipped, not shoved, to ensure good electrode contact with the skin. z You may choose to use a skin treatment or preparation that is recommended by your physician. Apply, let dry, and apply electrode as directed. This will both reduce the chance of skin irritation and extend the life of your electrodes. z Avoid excessive stretching of the skin when applying electrodes, this is best accomplished by applying the electrode and smoothly pressing it in place from the center outward. z When removing electrodes, always remove by pulling in the direction of hair growth. z It may be helpful to rub skin lotion on electrode placement area when wearing electrodes. CONNECTING THE DEVICE 1. Prepare the Skin Prepare the skin as previously discussed and according to instructions provided
