Wearing
Comfortably, but snugly, tighten the watch around your wrist, at least one finger width above
your wrist bone.
Note: Wearing the watch too loosely may impact the accuracy of the heart rate measurement.
When wearing the watch during workouts, which involve a great deal of wrist motion (such as
weightlifting), wearing the watch as far above the wrist as possible will provide the most
accurate heart rate measurement.
Your watch may be operated with both the touchscreen and the physical buttons. During
workouts you may wish to prevent accidental operation of the touchscreen and/or buttons and
can do so by enabling button lock once the workout is started. This feature is enabled and
disabled by holding the back button (lower left button) until the lock icon appears or
disappears.
Watch Updates
Periodically your watch will requires updates. These updates may be software related, or for
updating the satellite A-GPS data. A-GPS updates occur every couple of days to insure best GPS
performance for your outdoor workouts.
Note that updates such as A-GPS take less than a minute, but major software updates could
take as long as 15-20 minutes to complete. While an update is in process both the app and
watch will display the progress towards completion.
Most updates will start automatically when you sync the watch to the mobile app, but at any
time you can check for available updates on the app by clicking on the watch, on the dashboard
screen and scrolling down to "check for updates".
You can verify the version of software on your watch by looking at "Firmware version" just
below "Check for updates" on the mobile app or by going to settings, about on the watch.
You can verify when the A-GPS was last updated on the watch from the settings, about screen
on the watch. If it has been seven days or more since it was updated, it is best to sync the
watch with the mobile app prior to performing an outdoor workout for quickest GPS sync and
best GPS accuracy.
