Getting to know your Fitbit Flex 2
This section tells you how best to wear, navigate, and recharge your tracker.
Wrist choice and dominant hand
For greater accuracy, your tracker needs to know which wrist you wear it on (right or
left) and which hand you consider dominant (right or left). Your dominant hand is the
one you usually write or throw with.
During setup you’re asked to choose the wrist where you're going to wear your
tracker. Should you later decide to move your tracker to the other wrist, change the
Wrist setting. You can also change your dominant hand at any time with the
Handedness setting. Both settings are found in the Account section of the Fitbit app
or in the Personal Info section of your fitbit.com dashboard settings.
Understanding the indicator lights
Your Flex 2 has five indicator lights that flash various patterns depending on what
the tracker is doing. One light changes color while the other four are always white.
First-time setup
The first time you put your tracker in the charger before you set it up (pair), your
Flex 2 will flash and vibrate to greet you. The top light changes color several times
before flashing blue continuously.
When you put the tracker in the wristband and begin the pairing process, all five
lights flash in a looping pattern until you’re prompted to double tap the tracker.
When pairing is done, all five lights blink twice and you’ll feel two short vibrations.
Charging
While Flex 2 is charging, each pulsing indicator light represents progress towards the
total charge in increments of 25%. When Flex 2 is completely charged, a green light
flashes and then all five lights shine for a few seconds before turning off.
Updating
We occasionally make free feature enhancements and product improvements
available through firmware updates. During an update, all five lights on Flex 2 flash in
an upward pattern. If an update can’t finish, a blue light blinks and you’ll receive an
alert in the Fitbit app.
