The TapXR comes in two parts; the Sensor and the wristband (Band). Once you have selected the best fit for your wristband, you can attach the XR sensor. This modular design allows you to quickly and easily swap your XR to other band colors or wrist wearables.
To assemble your XR, snap the Sensor into place by lining up the dot on the Sensor with the dot on the bottom of the band and snapping it into the cradle. If the Sensor feels loose or falls out easily, or if it does not slide forward easily, ensure the dots are aligned and try again.
