Using your Flex

Wearing your Flex

The Fitbit Flex is designed to be worn on your wrist, inserted in the provided wristband. If you prefer to track your progress discreetly, you can remove the tracker from your wristband, and keep it in your pocket.

Your Flex can be worn on either wrist, though you may see a difference in the number of steps tracked while wearing it on the wrist of your dominant hand.

Dan Lavelle > Need to confirm whether we will have settings to change dominant vs. non-dominant hand. It would go here.

How to secure your wristband

Your Flex comes with a large and a small wristband. Select the option that best fits your wrist.

Your wristband should be comfortably tight, much like you would wear a watch.

Line up the peg over the holes in the band. Press down to snap the peg into the holes.

To change wristbands, remove the tracker from the wristband, as well as the peg that is used to fasten the wristband to your wrist. Once removed, you can insert them into your wristband of choice.

Using your Flex in wet conditions

While your Flex is primarily designed for tracking steps, the tracker itself may be worn while you are in the shower, working out, or swimming.

The Fitbit Flex is sweat-proof, rain-proof, and waterproof to a depth of ten meters.

Dan Lavelle > Do we want to include a recommendation to not use it at that depth? Do we want to include this at all?

LED Indicator Lights

Your Flex features an OLED (Organic Light-Emitting Diode) display that consists of 5 LED Indicator Lights. These lights communicate a variety of feedback to you, including; Goal progress, Battery charging, Sleep mode, and more.

For more information on how to understand these patterns, see http://help.fitbit.com.

Dan Lavelle > Until we have final firmware, and line-art to display the various light patterns, we'll be directing customers to our website, where we can document this with more flexibility. Feedback is welcome.

Battery life and power

Battery life

Your Flex comes equipped with a rechargeable Lithium-ion polymer battery.

Under normal use, the battery on your Flex should last approximately five days before requiring a charge. You can check the level of your battery by logging into the Fitbit.com Dashboard, and clicking on your Profile Name.

Charging your Flex

You can charge your Flex by plugging the provided Charging cable into an available USB port on your computer, and inserting your Flex into the bracket, with the grey triangle facing away from you.

Your Flex will progressively illuminate the LED Indicator Lights as it charges, with each light representing 20% of the maximum charge. Once all five lights are lit, your Flex is fully charged.

Memory

Your Flex stores minute-by-minute data for synchronization for two weeks. After two weeks, that data is converted to a daily total, which is stored for an additional two week period.

Any time you sync your Flex, this data is uploaded to your Fitbit.com Dashboard, and securely stored on Fitbit's servers. As long as you sync your Flex within thirty days of activity, you will be able to transmit that data to your Fitbit.com Dashboard.

NOTE: Every night at midnight, your Flex will reset your progress towards your daily goal. This does not delete the data stored on your tracker. That data will be uploaded to your Fitbit.com Dashboard the next time you sync your Flex.

The time this reset occurs is based on the Time Zone set on your Fitbit.com profile.

What Fitbit Flex tracks

Like other Fitbit trackers, your Flex can track the following activities:

• Steps taken
• Calories burned
• Distance traveled
• Active minutes
• Hours slept
• Quality of sleep

Setting goals with Flex

Your Flex is designed to track your progress to a specific goal which you define on your Fitbit.com Dashboard. Goals can be set for steps taken, calories burned, or distance traveled.

To choose the goal you want to track:

1. Log in to your Fitbit.com Dashboard.
2. Click your Profile name.
3. Click Account Settings.
4. Click Device Settings.
5. Next to Primary Goal, click change.
6. Choose your goal.

NOTE: You can only track one goal at a time, but you can change your goal at any time using by logging in to your Fitbit.com Dashboard.

Dan Lavelle > Images or line-art would be helpful here. Client is not currently final, but something akin to the goals screen on the client would be ideal.

Once you've chosen which activity you want to track, you can set a value for that goal on your Fitbit.com Dashboard (e.g. walking six miles, or burning 2900 calories).

When you tap your Flex twice with your finger, the LED Indicator Lights will illuminate to show how much of your goal you've accomplished. Each fully lit indicator represents 20% of your total goal.

A blinking light represents your current progress towards your goal.

When you reach your goal, your Flex will vibrate and flash the LED Indicator Lights to let you know you're there.

Tracking sleep with Flex

Your Flex can also track the hours you sleep, and help you understand the quality of that sleep by tracking your movement and restlessness while you're asleep.

To enter sleep mode, tap your Flex rapidly for one to two seconds. Your Flex will vibrate and display two slowly dimming lights to indicate that sleep mode has begun.

NOTE: When your Flex is in sleep mode, goal progress will not be displayed if you tap twice. Instead, your Flex will alternate two blinking lights, back-and-forth, to represent that you are currently in sleep mode.

When you wake up, tap your Flex rapidly for one to two seconds to exit sleep mode. Upon exiting sleep mode, your Flex will vibrate and display all five LED Indicator Lights.

If you enter or exit sleep mode by mistake, you can always adjust your actual time asleep on the Fitbit.com website. Since your Flex is still tracking your movement during this time, it can accurately represent your sleep quality, even when manually entering your sleep and wake times.

Silent Alarms

Your Flex can gently vibrate to wake or alert you using the Silent Alarm feature. You can set alarms using your computer for a mobile device.

Silent Alarms can be configured to recur on multiple days of the week (e.g. 8:00AM, every Sunday)

You can set up to eight alarms on your Flex at once.

NOTE: Setting multiple alarms may diminish the battery life of your Flex. If you find that you must charge your battery more often, you may want to reduce the number of Silent Alarms configured on your Flex.
