2BFPM-PERI-2Wearable Bio-sensor

Safety Manual General Use Wearing the device • The Peri device is worn under the breast on either the right or left side of the body. It is secured to the skin using the supplied adhesive patch only. The minimum recommended wear time for the patch is 7-10 days but it is designed to be worn for up to 14 days. • When removing the adhesive, pull the edge of the adhesive and peel off. Do not pull the device from the skin to remove the adhesive. • After removing the adhesive patch, gently cleanse the skin with mild soap and water. When reapplying the device, switch to the other side of the body, to allow the skin to rest. Avoid prolonged use without repositioning or replacing the adhesive patch. • For optimal results it is recommended to keep the patch on for at least 7 days. Removing the patch earlier than this can cause irritation and redness at the application site. • If the device needs to be removed earlier than 7 days, it is recommended to leave the adhesive in place and detach the device from the adhesive. Removing the patch in the shower under warm running water will make it easier to remove if needed. When re- attaching the device, use a new adhesive on the other side of the body. • Peri is designed for 24/7 usage and can be worn during showers and baths. It has been tested to an IPX8 rating, meaning it is dust-tight, providing full protection against dust ingress. The device is resistant to immersion in water up to a depth of 1 meter for a maximum of 60 minutes. Remove the device if swimming for longer than 60-mins, diving, snorkelling or other deep-water immersion. • Peri is designed to be worn in temperatures ranging from -10°C to 45°C (14°F to 113°F). Avoid exposing the device and batteries to excessive heat. Remove the device if using a sauna or other hot environment, as there is a risk the metal plates at the back of the device could heat up and cause pain or skin damage. Storage and maintenance • If the device and batteries are stored, they should be kept in a dry location between 0°C to 35°C (32°F to 95°F) • Do not use harsh chemicals, solvents, or abrasive cleaners, as these may damage the materials. Ensure the device is completely dry before reattaching or wearing. • This product contains small parts that could present a choking hazard. Keep out of reach of young children and pets when not in use. • When traveling, consult with your airline about their policy for lithium-ion batteries. Charging the device • This device comes with two interchangeable rechargeable lithium-ion batteries. The batteries provided with this product comply with applicable safety standards, including IEC 62133 (Safety requirements for portable sealed secondary lithium cells and batteries). These batteries are designed to last for the lifetime of the product under normal use. • Only manufacturer-approved batteries should be used. Use of unapproved batteries could present a fire hazard, risk of explosion, or device malfunction, and will void the warranty. Handle batteries with care when inserting or removing them from the device. • The Peri charger is not water resistant and is intended for indoor use only. Charging should be performed at 0°C to 45°C (32°F to 113°F) Do not use or store the charger in humid environments like bathrooms. Do not expose the charger to heat, such as in a vehicle or directly in the sun and do not charge Peri in such an environment. • Use only the charging cradle and USB cable provided with this product. The charging cradle is certified by the U.S. Department of Energy (DoE). This charging cradle is designed to be charged using a safety-certified power supply (power adapter) that meets applicable local regulatory requirements. The power supply should meet the energy efficiency requirements set by the U.S. DoE and provide an output of 5 volts DC (volts direct current) and a maximum output current of 1A (amperes) via a standard USB port. Using an unapproved power supply, or exceeding the recommended voltage or current, may result in overheating, fire, or damage to the product and void the warranty. • Do not puncture, crush, disassemble, or short-circuit the device or batteries • Do not expose the device or batteries to fire, explosion, or another hazard. If a battery or the device emits smoke, excessive heat, swelling, or a burning smell, stop using it immediately and contact the manufacturer. • The Peri charging cradle contains magnets. Keep away from items that may be sensitive to magnetic fields, such as credit cards, key cards, and implantable medical devices. Health Warnings • Peri is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent any medical condition or disease. The information provided by this device and its accompanying app is for informational purposes only and should not be considered medical advice. • If you have a pacemaker or other internal electronic device, consult your physician before using the Peri device. • If you make any changes to your lifestyle or behaviour based on data from Peri, you agree you do so at your own risk. You should always consult a physician if you have any questions regarding a medical condition or any changes you intend to make to your lifestyle choices based on information from Peri. Never disregard or delay in seeking professional medical advice because of something you’ve read from the Peri app. • Peri relies on sensors that track your motion, skin conductivity, temperature, blood volume changes, and other metrics. The translation of this data into menopausal symptoms is intended to be a close estimation of your activity and symptoms but may not be completely accurate. The information and guidance provided by Peri may be misleading if your physiological functions and responses differ significantly from population averages due to medical conditions or rare natural differences. The reporting of hot flushes, night sweats, sleep disturbance, anxiety and other readings are for reference only, and no …

When implement into the system, the frequency resonant might be off-tune due to the loading of surrounding components especially metal plane. This off-tune can be compensated through matching. Although module manufacturers specify a peak gain limit, it is based on free-space conditions. The peak gain will be degraded by 1 to 2dBi in the actual implementation as the radiation pattern will change due to the surround components. As such, during selection of antenna, you can select one with high peak gain to compensate for the loss. Molex can offer assistant to choose the best location and best tuning in-order to meet this peak gain requirement.
