Activity Tracking

My daily step count does not appear
The daily step count is reset every night at midnight.
If dashes appear instead of your step count, allow the device
to acquire satellite signals and set the time automatically.
My step count does not seem accurate
If your step count does not seem accurate, you can try these
tips.
Wear the device on your non-dominant wrist.
Carry the device in your pocket when pushing a stroller or
lawn mower.
Carry the device in your pocket when actively using your
hands or arms only.
NOTE: The device may interpret some repetitive motions,
such as washing dishes, folding laundry, or clapping your
hands, as steps.
The step counts on my device and my Garmin
Connect account don't match
The step count on your Garmin Connect account updates when
you synchronize your device.
1
Select an option:
Synchronize your step count with the Garmin Connect
application ( (Using Garmin Connect on Your Computer,
page 18)).
Synchronize your step count with the Garmin Connect
Mobile app ( (Manually Syncing Data with Garmin
Connect Mobile, page 14)).
2
Wait while the device synchronizes your data.
Synchronizing can take several minutes.
NOTE: Refreshing the Garmin Connect Mobile app or the
Garmin Connect application does not synchronize your data
or update your step count.
The floors climbed amount does not seem accurate
Your device uses an internal barometer to measure elevation
changes as you climb floors. A floor climbed is equal to 3 m
(10 ft.).
Avoid holding handrails or skipping steps while climbing
stairs.
In windy environments, cover the device with your sleeve or
jacket as strong gusts can cause erratic readings.
My intensity minutes are flashing
When you exercise at an intensity level that qualifies toward
your intensity minutes goal, the intensity minutes flash.
Exercise for at least 10 consecutive minutes at a moderate or
vigorous intensity level.
Acquiring Satellite Signals
The device may need a clear view of the sky to acquire satellite
signals. The time and date are set automatically based on the
GPS position.
1
Go outdoors to an open area.
The front of the device should be oriented toward the sky.
2
Wait while the device locates satellites.
It may take 30–60 seconds to locate satellite signals.
Improving GPS Satellite Reception
Frequently sync the device to your Garmin Connect account:
Connect your device to a computer using the USB cable
and the Garmin Express application.
