Scan Monitor
Solutions:
● Make sure your wrist and your ScanWatch are clean and dry. Water and sweat can
cause a poor recording.
● Ensure that your ScanWatch, arms, and hands remain still during recordings.
● Ensure that you have completed all of the on-boarding steps in the Withings app on your
smartphone.
Problem 7.1.2: I have an inconclusive measure. It looks like the ECG measure presents a lot of
artifacts, noise, or interference in my recording.
Solution:
● Rest your arms on a table while you take a recording. Try to relax and don't move too
much.
● Tighten the band so that the back of the watch is in contact with the skin of the wrist.
When moving the watch slightly, the skin in contact with it should move with it.
● Move away from any electronics that are plugged into an outlet to avoid electrical
interference.
Problem 7.1.3: The ECG waveforms appear upside down.
Solution:
• The device orientation may be set to the wrong wrist. On your smartphone, go to the Withings
app. Tap Devices > More Settings > Device Orientation.
All data recorded during an ECG measurement is saved to the HealthMate app on your
smartphone. If you choose to, you can share that Information by creating a PDF.
7.2 Troubleshooting for SpO2 measurements
Problem 7.2.1: The ScanWatch indicates that I am not staying still during SpO2 measurements.
Solution:
● Ensure that your ScanWatch, arms, and hands remain still during recordings.
● Ensure that your hand is comfortably resting on a flat surface.
● Do not move or talk during the entirety of the measurement.
Problem 7.2.2: I have an inconclusive SpO2 measurement.
Solution:
● Ensure that you have completed all of the on-boarding steps in the Withings app on your
smartphone.
● Rest your arms on a table while you take a recording. Ensure that your palm is open and
try to relax your hand.
● If you have low skin perfusion (for instance due to low temperatures), scrub your wrist at
the watch location to increase skin perfusion.
● Make sure that your ScanWatch is not loose on your wrist. Tighten the band until it is
snug but comfortable, and the watch stays in place even when you are moving. Wearing
the watch closer to the elbow can help obtain a better fit.
● Push slightly on the top of the watch with two fingers to improve the contact between the
skin and the watch.
