For example, during an exercise you can tap the pause icon in the lower right or tap the Select button next to it instead.

If your tracker has one of the following problems, it may be fixed by a restart:

• Your tracker isn't syncing
• Your tracker isn't responding to button presses, taps, or swipes
• Your tracker is charged but doesn't turn on
• Your tracker isn't tracking your steps or other stats

For restart instructions, choose your tracker below.

Note: Restarting your tracker turns it off and on without deleting any activity data. If your tracker saves notifications, a restart deletes them.

Follow these steps to restart your Fitbit Blaze: 

1. Press and hold the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen. This should take less than 10 seconds.
2. Let go of the buttons.
3. If your tracker doesn't work normally, use the instructions in How do I turn off my tracker? to turn Blaze off and back on again.

If you need additional help contact Customer Support.

Multisport mode on Fitbit Blaze lets you see real-time stats and a workout summary for the exercise you select, then saves the information in your exercise history. Certain exercises offer connected GPS tracking as described in Does my Fitbit tracker have GPS?

FIRST-TIME SETUP

If you plan to use connected GPS, verify the GPS-related settings on your phone:

• FITBIT APP FOR IOS

• First, make sure you can track your run, walk, or hike when you're out of Wi-Fi range:
  1. Open Settings and tap Cellular.
  2. Make sure Cellular Data is turned on.
• Next, ensure that your GPS can continue tracking when your phone is locked:
  1. Open Settings and tap General.
  2. Tap Background App Refresh, find the Fitbit app, and make sure it is turned on.
• Lastly, make sure your phone can identify your location:
  1. Open Settings and tap Privacy.
  2. Tap Location Services and make sure it’s turned on.
  3. Find Fitbit in the app list and make sure it's set to While Using the App or Always.

• FITBIT APP FOR ANDROID

The verification steps for these platforms vary widely depending on the specific mobile device. If you're unsure how to verify anything mentioned, consult the instructions provided by your device manufacturer.

1. Make sure your phone can track your activity when you're out of Wi-Fi range. This is usually achieved by making sure Cellular Data is turned on.
2. Make sure GPS can continue tracking while your phone is locked.
3. Make sure your phone can identify your location.This is usually achieved by enabling Location Services within your privacy settings.

To change the Exercise menu or make sure the exercise you want to track is included, see How do I customize the Exercise menu on my tracker?

If you want to receive time or distance-based updates (splits) on your Blaze during a run, turn on run cues in the Fitbit app. To find run cues, tap Account > Blaze > Exercise Shortcuts > Run (on Windows 10 mobile devices, tap Free Run). 

TRACKING AN EXERCISE

To use multisport mode:

1. On your tracker, swipe to the Exercise screen and tap it, then swipe to find the exercise of your choice.

   If you see a gear icon in the lower left corner, that exercise offers connected GPS. Tap the gear to see an option for turning GPS on or off. Press the Back button (left) to return to your exercise.

2. Tap the exercise to select. You’ll see the Let’s Go! screen.

   If you chose a connected-GPS exercise, you’ll see a phone icon in the top left. The dots mean your tracker is looking for the GPS signal. When the phone icon turns bright and the tracker vibrates, you know GPS is connected. Note that a weak GPS signal may cause your route and other activity data to be inaccurate.
   

3. Tap the screen’s Play symbol or press the Select button (lower right) to begin tracking your exercise. A stopwatch appears showing your elapsed time. Tap or swipe up and down to scroll through your real-time stats or check the time of day.
   
4. When you’re done with your workout or want to pause, tap the pause icon or the Select button (lower right).
5. To see a summary of your results, tap the flag icon or press the Action button (upper right).
   
6. Tap Done or press the Back (left) button to close the summary screen.

Syncing your tracker stores the workout in your exercise history. There you can find additional stats and see your route if you used connected GPS.

If you can't update your tracker, try the instructions below.

UPDATE FAILURES

If the connection between your tracker and mobile device is interrupted during the update, you may see this image:

Try these steps to resolve the problem:

1. Turn your tracker off and on again using the instructions in How do I restart my tracker?
2. Reboot your mobile device.
3. Try the firmware update again. If it doesn't work, on a different mobile device or computer (if available) log into your Fitbit account and try updating your firmware.
    

   Note that if you get notifications from your mobile device on your tracker, before you can use a different device or computer you need to follow the instructions in Why won't my tracker sync to another device or computer?

4. For assistance, please contact Customer Support.

If the update fails and you see this image, you'll be unable to use the tracker until the error condition is resolved:

In this case tap a screen or press a button to return to the clock and try the update again. (If you see "fitbit.com/setup"; follow the instructions in How do I set up my tracker?) If the update doesn't work, restart your tracker and try again.

LOW BATTERY OR LOW/HIGH TEMPERATURE

If you see the critically low battery screen when attempting a firmware update, charge your Blaze and try the update again.

Likewise if you see a temperature screen, try the firmware update again when Blaze has cooled off or warmed up.

Blaze is too warm	Blaze is too cold

If you receive call, text, or calendar notifications on your Fitbit tracker, your tracker has a Bluetooth "bond" with the mobile device that sends the notifications. This bond prevents the tracker from syncing with another mobile device or a computer.

To quickly and temporarily disable the bond, turn off Bluetooth on your mobile device. You can turn it back on later to resume syncing.

If you no longer use notifications, remove the bond:

1. Go to Settings > Bluetooth on your mobile device to to see a list of associated Bluetooth devices. This list might contain only your Fitbit tracker or also include devices like wireless speakers, headsets, etc.
2. Tap your tracker and choose "Forget This Device" or "Disconnect" (exact language will differ depending on your operating system).

You can now set up your tracker using another mobile device or computer. For instructions see How do I set up my tracker?

If your battery isn't charging, test the solutions below. If your battery is draining too quickly after a charge, see Can I improve my tracker's battery life?
 

If you've tried all four solutions but your tracker won't charge, contact Customer Support.
