===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. | |||
