Ⅳ. Frequently Asked Question

FITTO is a device that provides and monitors numerous muscle measurements of specific body regions using near-
infrared spectroscopy (NIRS) technology. Eight discrete wavelengths of DMW-NIRS penetrate the scan site’s surface
tissue to calculate the concentration of chromophores and to measure muscle value. The results can be viewed in
the FITTO mobile app, paired via Bluetooth, to provide integrated services for users.

3. Scanning and Results
•Q: The device is paired, but when I press the top button to start a scan, the following message
pops up: “Connected. Battery Low. Firmware update needed. Please, connect your charger to
update.”
•A: The device battery is running low (indicated by an amber light flashing every 0.6 seconds). To
charge the device, plug the device charger directly into a wall outlet.
Note: Using multiple Bluetooth connections at the same time may interfere with pairing
Note: If your device requires a firmware update, p.11 for more information.

•Q2: “Something went wrong” message keeps popping up when I try to scan my body.
•A2: Try these troubleshooting tips:
1. Check to see whether your network or Bluetooth connection is stable
2. You will receive this message if the scanning period is too short. Check if the device light
is flashing blue—it means the device is currently scanning. Hold the device in place until
the light stops flashing and the device “beeps” to successfully input a scan from FITTO to
your smartphone or tablet.
3. Make sure the scanning area on your body is clear of excess moisture and hair, in case
there is interference with the scanning device.
•Q3: My scan results keep changing drastically when I use the device!
•A3: Your results may be inconsistent if you did not scan the same location as your previous
sessions. See p.12-p.13 for more information on how to consistently scan your muscles on the
same location. You can also check to see if your general and physical information (e.g. weight,
waist circumference, etc.) are up to date!
•Q4: I have had my body composition measured before, and it is not the same as my FITTO scan
results.
•A4: Traditional BIA-based methods of measuring body fat can have an error margin greater than
5%. This is because Bioelectric Impedance Analysis (BIA) methods require estimation after
determining a response time to body water content via electrical impulse, in order to calculate
mass percentages. This means that BIA scans are not scanning your muscles or fat directly, but by
using the body’s water content as a base measurement to calculate mass percentages.
FITTO uses Near-Infrared Spectroscopy (NIRS) technology instead. This technology refers to an
electromagnetic wavelength corresponding to about 780 to 2500 nm and has been used to
measure tissue chromophores to describe human health. The best-known equipment is the pulse
oximeter, which measures the oxygen saturation of patients in hospitals. The device uses light
sources of 8-wavelength NIR LED (Light Emitting Diodes) to calculate oxy-hemoglobin, deoxy-
hemoglobin, water, and lipid by measuring tissue absorption and scattering during photon
migrations. NIRS technology was developed in the 1990s and has been used in various fields for
decades. With the development of light source technology, it is safely used non-invasively on the
human body, and it is developing into a technology that enables precise measurement. FITTO is
the only palm-sized portable device that can accurately measure and record body composition
such as muscle mass and body fat mass.
