===Failure to detect wrist===
TeltoHeart detects the wrist using light-based sensors (photoplethysmography), which measure blood
volume changes beneath the skin by emitting and detecting light. Additionally, electrode leads in direct
contact with the skin detect electrical signals generated by the heart, confirming the presence of the
wrist. To ensure proper wrist detection:<br>
1. '''Ensure Secure Fit:''' Properly secure TeltoHeart around the lower arm, just above the wrist
bone, as illustrated in the user manual. A snug fit enhances the efficiency of both sensor
types.<br>
2. '''Check for Hairiness:''' Excessive hair on the wrist may hinder the performance of optical
sensors. Ensure the skin beneath the device is free from obstructions for accurate
readings.<br>
3. '''Assess Skin Contact:''' Anything obstructing direct skin contact, such as clothing or
accessories, can impact sensor functionality. Confirm unobstructed contact for optimal
wrist detection.<br>
4. '''Verify Device Positioning:''' Wear the device approximately 1 cm above your wrist bone.
Incorrect positioning may disrupt the alignment of sensors with the skin, affecting the
accuracy of detection.
