Index Scale Displaying Weight and BMI Only
If your Index Scale is only returning your weight and Body Mass Index values on the scale's display and the remaining metrics display a large X icon in the center of the display, ensure the following:
Stand on the scale with your bare feet. Wearing shoes and or socks will not allow the scale to measure the remaining metrics.
Dirty or callused feet may also prevent the scale from measuring the remaining metrics. Pores on the skin must be open for the technology to work properly.
Make sure that you are placing your feet at the center of the scale.
Prevent scratches on the scale by keeping the surface clean. There is a sensitive sensor layer on the top of the scale that is susceptible to scratching. Keep small pieces of dirt/grit off of the scale.
Clean the scale with a smooth cloth to remove any thin layers of film that may have accumulated from bathroom or other environments.
Confirm that your scale is running version 2.70 firmware or higher. You can view this information by signing into Garmin Connect web and selecting the Index Scale under the Devices widget.
