Indoor Activities
The D2 Air device 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 49
).
When running or walking with GPS turned off, speed, distance, and cadence are calculated using the
accelerometer in the device. 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. You can use an optional foot pod to record pace,
distance, and cadence.
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 device, such as a speed or cadence sensor.
Recording a Strength Training Activity
You can record sets during a strength training activity. A set is multiple repetitions (reps) of a single move.
1 Press .
2 Select Strength.
3 Press to start the activity timer.
4 Start your first set.
The device counts your reps. Your rep count appears when you complete at least four reps.
TIP: The device can only count reps of a single move for each set. When you want to change moves, you
should finish the set and start a new one.
5 Press to finish the set.
The watch displays the total reps for the set. After several seconds, the rest timer appears.
6 If necessary, select
, edit the number of reps, and add the weight used for the set.
7 When you are done resting, press to start your next set.
8 Repeat for each strength training set until your activity is complete.
9 After you complete your activity, press , and select
.
Calibrating the Treadmill Distance
To record more accurate distances for your treadmill runs, you can calibrate the treadmill distance after you run
at least 1.5 km (1 mi.) on a treadmill. If you use different treadmills, you can manually calibrate the treadmill
distance on each treadmill or after each run.
1 Start a treadmill activity (
).
2 Run on the treadmill until your D2 Air device records at least 1.5 km (1 mi.).
3 After you complete your run, press .
4 Check the treadmill display for the distance traveled.
5 Select an option:
• To calibrate the first time, enter the treadmill distance on your device.
• To manually calibrate after the first-time calibration, swipe up, select Calibrate & Save, and enter the
treadmill distance on your device.
Outdoor Activities
The D2 Air device comes preloaded with apps for outdoor activities, such as running and biking. GPS is turned
on for outdoor activities. You can add apps using default activities, such as cardio or rowing.
