4. Operating Instructions
4.1 Taking a Measurement
For accurate readings, always place the scale on a hard, flat surface. Avoid carpets or uneven flooring.
- Step onto the scale barefoot. Ensure your feet are positioned correctly on the four electrode pads.
- The scale will automatically turn on and begin the measurement process.
- Remain still until all measurements are displayed on the LCD screen (approximately 4 seconds).
- Your measurements will automatically be sent to the OMRON Connect app if your smartphone is nearby with Bluetooth enabled.

4.2 Automatic User Recognition and Guest Mode
The OMRON VIVA scale can recognize up to 4 registered users based on their weight and body composition data. If an unregistered user steps on the scale, it will default to guest mode.
- Registered Users: The scale will display the user number (e.g., 'U1', 'U2') once it identifies the user. Data will be saved to that user's profile in the app.
- Guest Mode: If the scale cannot identify a user, it will display 'Guest'. Measurements taken in guest mode will not be saved to a specific profile but can be manually assigned in the app if desired.
