The accuracy of heart rate measurements can be affected by factors such as incomplete fit, arm movement, and wearing the hand ring too tightly. To measure heart rate accurately, wear the hand ring correctly, relax, and remain still. Additionally, individual differences in skin color, hair, tattoos, and scars may also affect the accuracy of heart rate measurements.

The hand ring will vibrate and notify you of an incoming call 3 seconds after a call reminder is set up. However, you can customize the call reminder time in the Veryfit app according to your individual needs.

To charge the hand ring, remove it from the wrist strap and plug it into a USB port, being careful not to insert it the wrong way around. The charging progress can be seen by sliding the screen, but the screen won’t stay on during the charging process to conserve power. Under normal circumstances, it takes 1-2 hours to fully charge the hand ring. The standby time of the hand ring is about 35 days, and normal use lasts about 7 days. Note that enabling the automatic heart rate detection feature and vibration notifications can consume more power and affect the battery life of the hand ring.

To use the hand ring to remotely take photos, keep the hand ring connected to your phone via Bluetooth. Also, make sure to grant permission to the Veryfit app to access your phone’s camera. Once connected, simply raise your wrist and press the button on the hand ring to take a photo.
