Introduction It is intended to record and store electrocardiogram (ECG) rhythms, and transfer records to compatible mobile App for further research or analysis. It is not a medical device and should not be used for any medical purposes or any medical conditions. It is intended only for general wellness use. 2. Warnings  The ECG results (including regular heartbeat) do not guarantee that you are free from an arrhythmia or other health conditions. You should notify your physician of possible changes of your health.  Do not use the device to self-diagnose heart-related conditions. Consult with your physician before making any 2 medical decision, such as altering your use of any drug or treatment.  Do not continue to use the device until further instructed by a physician if your skin is irritated or inflamed around the electrodes.  The device makes no warranty for any erroneously collected data or information from misuse or malfunction as a result of abuse, accidents, alteration, negligence, or failure to maintain the products as instructed. The results made by this device are preliminary screening of cardiac conditions, not a complete diagnosis. All interpretations should be reviewed by a medical professional for clinical decision-making.  The device has not been tested for and is not intended for pediatric use.  Keep the device away from young children. Contents may be harmful if swallowed. 3  Do not take a recording while driving or during physical activity.  Do not store in extremely hot, cold, humid, wet, or bright conditions.  Do not take a recording if the electrodes are dirty. Clean them first.  Do not immerse the device in or expose the device to excessive liquid.  Do not drop or bump with excessive force.  Do not expose to strong electromagnetic fields.  Do not expose the device to a magnetic resonance (MR) environment.  Do not use with a cardiac pacemaker, ICDs, or other implanted electronic devices.  Do not use during cautery and external defibrillation procedures. 4  Do not place the electrodes in contact with other conductive parts including the earth.  Do not use with unapproved accessories. The use of unapproved accessories or transducers and cables may result in electromagnetic emissions or decreased electromagnetic immunity of this device and result in improper operation.  Do not use the device adjacent to or stacked with other equipment because it may result in improper operation. 3.
