By using any one of the outdoor activity profiles (i.e. swim, cycle, run), you are
activating the GPS automatically. If GPS is being used to calibrate altitude, the margin
of error is within approximately 165ft.
For best results, avoid locations with signal interference and allow GPS to locate your
position prior to starting an activity.
Note: GPS signal will be lost if the COROS device is submerged underwater. For
open water swimming, it is recommended to use freestyle strokes for better GPS
accuracy.
The COROS watch uses an optical heart rate monitor, that flashes a green LED light
onto the wrist to measure heart rate. To improve accuracy of the heart rate monitor,
please fasten your watch band and make sure the watch rests securely on your wrist.
Note: The heart rate monitor is not for medical use and may be subject to external
interference. Always consult your physician before starting an exercise program.
Heart rate data is for reference only and COROS shall not be held responsible for the
consequences of any readings.
Note: Using navigation will automatically turn on the GPS. Please use your best
judgement during navigation.
If your COROS device supports navigation functionality, you may pre-load the route
to the device as a .GPX file from the COROS App.
If your COROS device supports mapping functionality, you may access it from the
main menu under Maps.
Note: COROS uses a third-party provider for map data information. Please read the
terms and conditions of the provider before downloading and using the mapping
function. COROS is not responsible for the accuracy of the data and the stability of
the connection.
The optical oximeter sensor flashes an infrared light onto the wrist to determine the
user’s blood oxygen level. In order to ensure the accuracy of the oximeter sensor,
please fasten your watch band and make sure the watch fits securely against your
wrist.
The optical oximeter is available on select COROS watch models. To see a complete
list of compatible models, please visit www.coros.com.
Note: The oximeter sensor is not for medical use and may be subject to external
interference. Certain circumstances may cause the blood oxygen reading to be
inaccurate. Blood oxygen readings are for reference only and COROS shall not be
held responsible for the consequences of any readings.
