Adjusting brightness 
This setting controls the brightness of the text and images on your Blaze. The default 
setting, called Auto, adjusts brightness based on the ambient lighting conditions. If 
you prefer a persistent brightness level, you can change the default to:

you find Brightness.

Turning Quick View on or off 
Quick View causes your Blaze to wake when you lift or flick your wrist towards you. If 
Quick View is turned Off, press any button or double tap to wake your tracker. To 
adjust this setting, swipe to the Settings menu and tap the screen. Swipe up until you 
find Quick View. 
Adjusting the heart-rate tracker 
Your Blaze uses PurePulse™ technology to track heart rate automatically and 
continuously when the heart-rate tracker is on. The Heart Rate Tracking setting has 
three options: 
•!Auto (the default) —Heart rate tracking is generally active only when you are 
wearing your Blaze.  
•!Off —Heart rate tracking is never active.  
•!On—Heart rate tracking is always active; you may want to choose this option if 
your heart rate isn’t being tracked even though you are wearing your Blaze.  
To adjust this setting, swipe to the Settings menu and tap the screen. Swipe up until 
you find Heart Rate Tracking.

Updating your Fitbit Blaze 
Free feature enhancements and product improvements are occasionally made 
available through firmware updates. We recommend keeping your Blaze up to date.  
You’ll be notified in the Fitbit app when an update is available. After you start the 
update, you’ll see a progress bar on your tracker until the process is complete, 
followed by a confirmation message.  
Note that updating your Blaze takes several minutes and may be demanding on the 
battery. For this reason we recommend putting your charger in the charging cradle 
before updating.

Troubleshooting your Fitbit Blaze 
If your tracker is not working properly, review our troubleshooting information 
below. For other problems or more details, visit http://help.fitbit.com. 
Heart-rate signal missing 
Blaze continuously tracks your heart rate while you’re exercising and throughout the 
day. Occasionally the heart rate tracker may have difficulty finding a good enough 
signal to show a heart rate.  
 
If you’re not getting a heart rate signal, first make sure you’re wearing your tracker 
correctly, either moving it higher or lower on your wrist or tightening or loosening 
the band. After a short wait, you should see your heart rate again. If a heart rate 
signal is still not found, check your Heart Rate Tracking setting in your tracker’s 
Settings menu and make sure it’s set to On or Auto.  
Unexpected behavior 
If you experience one of the following problems, it may be fixed by restarting your 
tracker:       
•!Not syncing despite successful setup 
•!Not responding to button presses, taps, or swipes 
•!Unresponsive despite being charged  
•!Not tracking your steps or other data 
Note:  Restarting is not the same thing as shutting down your tracker. The Shut down 
option is available in the tracker’s Settings menu to help you preserve battery 
life. Restarting your tracker as described below reboots the device. Restarting 
your tracker does not delete any data. 
 
To restart your tracker:

1.!Press and hold the Back and Select buttons (left and bottom right) until you 
see the Fitbit icon on the screen. This should take less than 10 seconds.  
2.!Let go of the buttons. 
Your tracker should now work normally.
