&you Pulse User Manual

Device Overview

The Pulse device includes:

1. Sensor Module — Collects physiological and motion data when worn.
2. LED Light — Indicates charging status and device power status.
3. Side Button — Used to power the device on and off.
4. Charging Pins — Used to connect the magnetic charging cable.

Charging Time (0–100%)

Charging behavior is non-linear. Like charging your phone, the Pulse device typically charges faster at lower battery levels and slows as it approaches full capacity to help preserve long-term battery health.

In many cases, the device may reach approximately 50% charge within 30–45 minutes, while a full charge may take up to 3 hours, depending on power source, battery level, and environmental conditions.

Charging Recommendations:

• Partial charging is safe and encouraged.
• The device does not need to be fully depleted before charging.
• Use a standard, reliable power source (USB-C port or wall adapter).
• Avoid charging in extreme heat, direct sunlight, or wet environments.

LED Status Color — How to Know When It Is Fully Charged

While charging, the LED will fade in and out slowly. Once fully charged, the LED will turn solid green. Disconnect from the charger once the device is fully charged.

Cleaning the Device

Wipe the sensor area with a soft, damp cloth after workouts or extended wear. Do not use harsh chemicals or abrasive cleaners, and do not submerge the device to clean it.

Water Resistance

The Pulse has an IP68 rating (water-resistant in fresh water up to 1 meter for 30 minutes). Avoid prolonged hot showers, saunas, steam rooms, and contact with soaps, shampoos, or chemicals, as these can degrade water resistance over time.

Intended Use and Medical Limitations

Use the Pulse device only for the purposes described in its labeling and User Manual. The Pulse device is not a medical device.

Unless a feature is expressly identified in the Pulse device labeling as FDA-cleared or otherwise authorized by any other medical device regulatory authority for a medical purpose, that feature and its outputs are intended for general informational and general wellness purposes. The Pulse device and its features are not intended to diagnose, treat, cure, mitigate, alleviate, monitor, predict, or prevent any disease or medical condition. Do not use the Pulse device or its data as a substitute for professional medical advice, diagnosis, treatment, or an FDA-authorized medical device. Do not disregard medical advice, delay treatment, or make medication or other clinical decisions based solely on Pulse device data.

The Pulse device is not an emergency monitoring or notification system. If you believe you may be experiencing a medical emergency, seek immediate medical assistance.

Health Conditions and Exercise

Consult a qualified healthcare professional before using the Pulse device if you:

• Have a cardiovascular, respiratory, neurological, circulatory, or other medical condition;
• Are pregnant;
• Have recently undergone surgery or experienced a serious illness;
• Have been advised to limit physical activity; or
• Have concerns about whether the Pulse device is appropriate for you.

Stop exercising and seek appropriate medical attention if you experience chest pain, faintness, dizziness, shortness of breath, unusual discomfort, or other concerning symptoms.

This device uses optical LED sensors (PPG) on the underside of the module to measure physiological signals. Do not stare directly into the sensor LEDs. The Pulse device may occasionally emit lights and flash. Consult your physician if you have epilepsy or are sensitive to bright or flashing lights.

Pacemakers and Other Implanted Medical Devices

If you have a pacemaker, implantable cardioverter-defibrillator, neurostimulator, insulin pump, or other implanted or body-worn electronic medical device, consult your healthcare provider and the medical device manufacturer before using the Pulse device.

The Pulse device and its charging accessories may contain magnets or components that emit radiofrequency energy. Keep components containing magnets at least six (6) inches (15 centimeters) from an implanted medical device, and do not place them in a pocket or directly over the implant. Follow any greater separation distance specified by the implant manufacturer.

If you suspect interference, stop using the Pulse device, move it away from the medical device, and contact your healthcare provider.

Skin Irritation and Allergic Reactions

This device is designed to be worn on the wrist. Prolonged contact, pressure, moisture, sweat, soap residue, cosmetics, or sensitivity to product materials may cause skin irritation.

• Wear the Pulse device securely, but do not tighten it too much.
• Keep the device, band, and underlying skin clean and dry.
• Do not place the device over wounds, rashes, irritated skin, or inflamed areas.
