  • Page 9 Wear FB424 Choose to wear FB424 around your wrist or in the clip accessory (sold separately). If you need to remove the band or attach a different band, see the instructions in "Change the band" on page . When you wear FB424 in the band, make sure your tracker is set to WORN On Wrist . When you wear FB424 in the accessory clip, make sure it’s set to CLIPPED On Body . For more information, see "Navigate FB424" on page . Placement for all-day wear vs. exercise When you're not exercising, wear FB424 a finger's width above your wrist bone. In general, it's always important to give your wrist a break on a regular basis by removing your tracker for around an hour after extended wear. We recommend removing your tracker while you shower. Although you can shower while wearing your tracker, not doing so reduces the potential for exposure to soaps, shampoos, and conditioners, which can cause long-term damage to your tracker and may cause skin irritation. For optimized heart-rate tracking while exercising: ● During a workout, experiment with wearing your tracker a bit higher on your wrist for an improved fit. Many exercises, such as bike riding or weight lifting, cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the tracker is lower on your wrist. ● Wear your tracker on top of your wrist, and make sure the back of the device is in contact with your skin. ● Consider tightening your band before a workout and loosening it when you’re done. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal). Handedness For greater accuracy, you must specify whether you wear FB424 on your dominant or non- dominant hand. Your dominant hand is the one you use for writing and eating. To start, the Wrist setting is set to non-dominant. If you wear FB424 on your dominant hand, change the Wrist setting in the Fitbit app:...
  • Page 10 From the Today tab in the Fitbit app, tap your profile picture FB424 tile Wrist Dominant. Wear FB424 in a clip Wear FB424 clipped to your clothing. Remove the bands, and place your tracker in the clip. For more information, see "Change the band" on page . To put FB424 in the clip: 1. If you previously wore FB424 on your wrist, change your device setting to CLIPPED On Body . For more information, see "Navigate FB424" on page . Note: Make sure FB424 is set to WORN On Wrist when you wear your tracker in the band. 2. Hold the tracker with the screen facing you. Make sure the time isn't upside down. 3. Hold the clip accessory with the opening facing you and the clip on the back facing down. 4. Place the top of the tracker into the clip opening and move the bottom of the tracker into place. FB424 is secure when all edges of the clip lie flat against the tracker. Note that when FB424 is set to CLIPPED On Body , certain features are turned off, including heart-rate tracking, automatic exercise tracking, and Active Zone Minutes. Clip Placement Wear FB424 on or close to your body with the screen facing outward. Secure the clip tightly to a shirt pocket, bra, pants pocket, belt, or waistband. Try out a few different locations to see what's most comfortable and secure for you. If you experience skin irritation when wearing FB424 on your bra or waistband, clip it to an external piece of clothing instead, such as your belt or pocket.
  • Page 11 Wear and care tips ● Clean your band and wrist regularly with a soap-free cleanser. ● If your tracker gets wet, remove and dry it completely after your activity. ● Take your tracker off from time to time. ● Your tracker may show minor wear over time. Always clean it with a soft cloth and avoid contact with hard surfaces. Change the band FB424 comes with a small band attached and an additional large, bottom band in the box. Both the top and bottom bands can be swapped with accessory bands, sold separately on fitbit.com. For band measurements, see "Band size" on page . Remove a band 1. Turn over FB424 and find the quick-release lever. 2. While pressing the quick-release lever inward, gently pull the band away from the tracker to release it. 3. Repeat on the other side. Attach a band 1. To attach a band, hold the band and slide the pin (the side opposite the quick-release lever) into the notch on the tracker. 2.
