This product complies with the general requirements for a safe medical device under applicable directives. However, this product alone is not meant to substitute for proper medical diagnosis, care, or treatment. Clinicians should not make drastic changes to a user’s lifestyle based solely on data from the armband. The SenseWear armband has been clinically validated for subjects between 7 and 65 years of age who are engaged in resting, ambulatory, stationary biking, motoring and weight-lifting activities, etc. Due to metabolic variations, subjects who are 1) outside this age range or 2) engaged in alternate or obscure activities may see decreased accuracy in the data. Any decisions based on the data from this device should be made only by medical or paramedic personnel and should consider the condition and lifestyle of the subject tested. The SenseWear® armband should not be used for life critical applications; improper usage may result in harm or even death to the wearer. Please be sure to verify equipment is connected and used compliant to UL1950. Intended Use The SenseWear® armband can be used as a monitor for applications such as: nutritional diagnostics, metabolic diseases, pediatrics, pulmonary and cardiac studies, geriatrics, internal medicine, occupational medicine, neurology, psychiatrics, sleep screening, and in general anywhere it is necessary to monitor caloric and energy consumption, movement, physical activity, quality of life, lifestyle, behavior and/or stress. Be sure that both your arm and the sensors on the back of the armband are cleaned daily. To clean the sensors, wipe with a soft, damp cloth. If you develop a rash where the armband comes in contact with your skin, discontinue Wear comfortably Be careful not to over-tighten the armband while on your arm. If, at any time, you feel constriction or loss of circulation, simply loosen the adjustable strap and re-fasten it to a more comfortable setting. Keep the SenseWear® armband and wireless communicator out of reach of children. Both products contain smaller, removable parts which can become choking hazards. The SenseWear® wireless communicator should not be used in airplanes, hospitals or locations where cellular telephones or electronic devices are prohibited. The equipment or system should not be used adjacent to or stacked with other equipment and if adjacent or stacked use is necessary, the equipment or system should be observed to verify normal operation in the configuration in which it will be used.

The armband is IP67 water resistant to 1 meter under water for 30 minutes. Loss of data may occur if the armband is under water for a longer period of time. Users with sensitive skin should avoid wearing the armband excessively. If you have sensitive skin, remove the armband 1 hour for every 24 hours of wear time to reduce potential for skin irritation. When the armband is on the arm, DO NOT connect it to the USB cable. There have been reports of scratches/cuts associated with the Velcro tab of the strap. The Velcro tab should be aligned with the strap to avoid contact with the skin. Also, excessively hot armbands, such as those left in a car in the summer, may cause skin burns if they are not allowed to cool before use. Check armband for sharp edges or damage before each use. • Data accuracy may become compromised if the sensing module is submerged in water. • The wing seal must be in good condition and the wing must be properly attached to the sensing module to avoid damaging the unit. • Do not get the sensing module wet while removed from the wing assemble as damage will occur. use and consult your physician before continuing regular use of the armband. The design of the armband involved many materials experts, physicians, and suppliers who are familiar with wearable materials and products. Each material was chosen for its precedent in other skin contact products or has been independently approved for skin contact. However, everyone’s skin is different and wearers with very sensitive skin may experience irritation or redness after wearing the armband. If this occurs, discontinue use and consult your physician. If you have known metals allergies, you should consult your physician prior to wearing. Do not wear armband when open sores are present. Maintenance Do not attempt to open the armband yourself. It contains no user-serviceable parts. Refer all servicing to qualified Service Personnel. Opening the armband yourself will void the warranty. Dispose of device in accordance with local, state, federal, or country specific regulations. To prevent possible damage to the USB cable, grasp the plug end when disconnecting the USB cable. Replace the cable if it becomes frayed. Avoid exposing the armband to extreme temperatures, direct sunlight, moisture, sand, dust, or mechanical shock. Handling Though the SenseWear® armband was designed for wearability and long-term use, it is a sensitive monitoring device. Rough handling can break internal components. Never drop or shock the armband and always store it in a safe place when not in use. important important 7 Disinfecting Wipe back of armband with soft cloth dampened with 70% isopropyl alcohol. Allow armband to dry for 5-10 minutes before wearing DO NOT STERILIZE THIS UNIT. Moisten a soft cloth or towel with mild disinfectant soap and water. Wipe and dry the skin-touching side of the armband. Never use solvents to clean the armband, only for disinfecting (see below). The adjustable strap should be hand-washed with mild soap and warm water, then air-dried. Machine drying should be avoided.
