Operational Manual
Step 1. Power on the device by tapping the START/STOP button.
Step 2. Gently place the tip of your index finger over the camera, so that it covers the lens completely.
Step 3. The readings will appear after a few seconds. The heart-shaped bars indicate measurement accuracy.
Hint: If you are getting wrong readings (or none at all), please try adjusting the position of your finger on the camera lens. Also, please be sure to take measurements in a well-lit environment if your device does not have a torchlight.
