Warnings The device must be kept out of reach of children. The safety of device for use during pregnancy or delivery has not been established. Do not place electrodes on front of the throat. This may result is spasms of the laryngeal and pharyngeal muscles. Do not place the electrodes over the carotid nerve. The device is not effective for pain of central origin (headaches). The device may interfere with electronic monitoring equipment (such as ECG monitors and ECG alarms). Electrodes should not be placed over the eyes, in the mouth, or internally. These devices have no curative value. The devices should be used only under the continued supervision of a physician. IF is a symptomatic treatment and as such suppresses the sensation of pain which would otherwise serve as a protective mechanism. Precautions/adverse Reactions Isolated cases of skin irritation may occur at the site of electrode placement following long-term application. Stimulation should be stopped and electrodes removed until the cause of the irritation can be determined. Effectiveness is highly dependent upon patient selection by a person qualified in the management of pain patients. If the device treatment becomes ineffective or unpleasant, stimulation should be discontinued until reevaluation by a physician/clinician. Always turn the device off before applying or removing electrodes. Skin irritation and electrode burns are potential adverse reactions.

ATTACHING THE LEAD WIRES 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 with your electrodes. Before attaching the electrodes, identify the area in which your physician/practitioner has recommended for electrode placement. 2. Connect lead wires to the electrodes Connect the lead wires to the electrodes before applying the electrodes to the skin. Note: Be sure all intensity controls for every Channel 1 and 2 of each unit are turned to the “OFF” position. 3. Place Electrodes on Skin Place the electrodes on the skin as recommended by your clinician. 4. Insert Lead Wire Connector to device Plug end of lead wire into the channel output receptacle to be used, pushing plug in as far as it will go. 5. Select Treatment Settings Check and be sure your unit is still set to the proper settings recommended by your physician/practitioner. 6.
