Usage Information
Vu Pro – EasySense And Stand Alone Operation
There are two fundamentally different ways to collect data using Vu Pro.
1.Using Vu Pro with EasySense software to capture data directly.
2.Using Vu Pro as a stand alone device, collecting data independently and then importing it into EasySense later for review and analysis.

Vu Pro – Quick Start Guide
1. Charging The Vu Pro
•Use the USB cable included.
•Connect to a computer, USB power hub, or USB mains charger (5 V, ≥ 500 mA).
•White flashing LED = charging (Vu Pro On), red, green and blue flashing, Vu Pro is off
•Solid green LED = fully charged, A full charge takes about 4 hours.
The status of the battery is shown on the main screen and is charged using the USB cable to a compliant supply. The battery level indicator is the following icon: 
2. Turn On The Vu Pro
•Press any front-panel button.
•The screen will light up and the blue LED will flash (Bluetooth advertising).
To turn off the Vu Pro:
•Let it sit idle for 2 minutes, or

Safety Recommendations
1. Small Parts and Accessories
Some accessories supplied with the Vu Pro, such as plug-in sensors, connectors, and USB cables, may contain small components that could present a choking hazard. These items should be kept out of the reach of very young children when not in use. Always ensure that loose parts are stored securely and that children do not handle small accessories without appropriate guidance.
2. Supervision for Young Users
The Vu Pro is designed for use in educational settings, including activities for younger learners. However, particularly those under the age of 8—should be supervised when connecting sensors, attaching accessories, or charging the device. Adult oversight helps ensure safe handling of cables, connectors, and external components, and supports proper use during experiments.
3. Electrical Safety Guidance
The Vu Pro charges using a low-voltage USB power source, but standard electrical safety practices should still be followed. Do not use damaged or frayed USB cables, and disconnect the device immediately if a cable or connector becomes hot or shows signs of wear. Keep all connectors dry and avoid charging or using the device near water or other liquids. Only use USB power supplies that meet the recommended specifications provided in this manual.
4. Educational Use of Heart Sensors
The built-in heart rate sensor and any associated accessories are intended solely for educational demonstrations and simple physiological investigations. They are not medical devices and must not be used for health assessment, diagnosis, or monitoring of medical conditions
