My device does not display the correct time
The device updates the time and date when you sync your
device smartphone or when your device acquires GPS signals.
You should sync your device to receive the correct time when
you change time zones, and to update for daylight saving time.
1
Hold the touchscreen, and select Settings > System > Time.
2
Verify the Auto option is enabled.
3
Select an option:
• Confirm that your smartphone displays the correct local
time, and sync your device to the smartphone (Using
Garmin Connect Mobile, page 13).
• Start an outdoor activity, go outdoors to an open area with
a clear view of the sky, and wait while the device acquires
satellite signals.
The time and date are updated automatically.
Acquiring Satellite Signals
The device may need a clear view of the sky to acquire satellite
signals.
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.
◦ Sync your device to the Garmin Connect Mobile app using
your Bluetooth enabled smartphone.
While connected to your Garmin Connect account, the device
downloads several days of satellite data, allowing it to quickly
locate satellite signals.
• Take your device outside to an open area away from tall
buildings and trees.
• Remain stationary for a few minutes.
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.
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.
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.
Improving the Accuracy of Intensity Minutes
and Calories
You can improve the accuracy of these estimates by walking or
running outside for 20 minutes.
