By using any one of the outdoor activity profiles (i.e. swim, cycle, run), you activate 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 signals 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.
If your COROS device supports navigation functionality, you may pre-load the route to the device as a .GPX file from the COROS APP.
Note: Using navigation will automatically turn on the GPS. Please use your best judgement during navigation.
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 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.
The COROS device supports many wireless ANT+ and Bluetooth Smart sensors. The first time you connect an ANT+ or Bluetooth Smart enabled sensor to the COROS device, navigate to Menu > Settings > Accessories > Add ANT+ or Add Bluetooth to complete the pairing process.
It is recommended you thoroughly clean your COROS device to remove excess sweat and debris after frequent usage. If not properly cleaned, residual sweat may corrode the device. To properly clean the device, please use mild soapy water and ensure the device remains dry when contacting the skin. If skin irritation occurs, remove the device immediately. Keep the heart rate monitor sensor and charging port clean and clear of debris (i.e. sand, sweat, dirt, etc.). Avoid excessive exposure to extreme hot or cold temperatures.
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.
The COROS device is equipped with a geomagnetic sensor, thermometer, barometer, gyroscope, and accelerometer. An accelerometer is used for detecting hand gestures, steps and the calculation of Caloric data. The compass uses a geomagnetic sensor to show directions. Both the thermometer and barometer will detect ambient temperature and atmospheric pressure.
Note: The data captured by these sensors may not be completely accurate and is for reference only.
The COROS device comes with a USB charging cable and a watch band. Please remove and clean the watch band regularly to avoid skin irritation.
Note: Please only use a COROS-branded charging cable to charge this device.
The COROS watch contains a Bluetooth module for smartphones and external sensor connection. The Bluetooth module uses a 2.4 GHz frequency and may interfere with inflight and ground communication devices.
Do not perform unauthorized battery replacement.
Avoid excessive exposure to extreme hot or cold temperatures. Do not submerge the battery.
Keep the battery away from children.
Accidental damages and improper operation may cause daily and workout data loss. Please sync the COROS device with the COROS APP regularly. Product repair may cause data loss.
