Viewing Your SpO2 Readings in Flight
WARNING
The SpO2 readings are intended for supplemental information only. Always defer to applicable flight
instruments for primary awareness.
The watch has a wrist-based pulse oximeter to gauge the saturation of oxygen in your blood (SpO2). During a
flight, the watch automatically takes pulse oximeter readings more frequently, so you can monitor your SpO2
percentage.
TIP: You can improve the accuracy of your SpO2 readings by turning on the All Day pulse oximeter mode
(Setting the Pulse Oximeter Mode, page95).
During a flight, scroll up or down to view the SpO2 data screen.
Your most recent reading appears as an oxygen saturation percentage and position on the color gauge.
NOTE: If you are too active for the watch to determine your oxygen saturation, dashes appear instead of a
percentage. You should remain stationary for up to 30 seconds while the watch reads your blood oxygen
saturation.
