Getting to know your Fitbit Flex

Using your Flex in wet conditions

Your Flex is water-resistant, which means it is rain-proof and splash-proof and can stand up to even the sweatiest workout.
Do not swim with your Flex. We also don't recommend showering with your Flex; though the water won't hurt the device, wearing it 24/7 does not give your skin a chance to breathe. Whenever you get your Flex wet, dry it thoroughly before putting it back on.

Understanding the LED indicator lights

Your Flex has 5 LED indicator lights. The lights behave differently depending on what the tracker is doing.

Goal tracking

The indicator lights illuminate as you hit 20% increments towards your goal. Tap your Flex to see your progress. When you reach your goal, Flex will celebrate by buzzing and flashing its lights.

Sleep mode

When you tap your Flex rapidly for one or two seconds to manually enter sleep mode, it will vibrate and display two slowly dimming lights. During manual sleep mode, two blinking lights alternate. After you tap your Flex rapidly to exit manual sleep mode, it will vibrate and flash all five lights three times and then display a spinning light pattern.

These light patterns only apply to manual sleep mode. If you let Flex detect your sleep automatically, no special light patterns appear.

Charging
While your Flex is charging, an indicator light will pulse to show the battery level every few seconds. Each indicator light represents progress towards the total charge. When the Flex has charged completely, all 5 indicator lights will blink.

Updating
If an update fails to complete, your Flex's LED indicator lights may cycle back and forth repeatedly, from left to right, and your Flex may no longer respond to taps, charging, or resets.

Alarms
When a silent alarm goes off, the Flex vibrates and the center light flashes.

With normal use, your Flex should last up to five days before needing a charge. You can check the level of your battery by logging in to Fitbit nd clicking on the gear icon in the top-right corner of the page.
