Indoor Activities
The D2 Mach 1 watch can be used for training indoors, such as running on an indoor track or using a stationary
bike or indoor trainer. GPS is turned off for indoor activities (Activities and App Settings, page 32).
When running or walking with GPS turned off, speed, distance, and cadence are calculated using the
accelerometer in the watch. The accelerometer is self-calibrating. The accuracy of the speed, distance, and
cadence data improves after a few outdoor runs or walks using GPS.
TIP: Holding the handrails of the treadmill reduces accuracy.
When cycling with GPS turned off, speed and distance data are not available unless you have an optional sensor
that sends speed and distance data to the watch, such as a speed or cadence sensor.
