Charge your tracker A fully-charged FB422 has a battery life of up to 7 days. Battery life and charge cycles vary with use and other factors; actual results will vary. Note: The FB422 charging cable has a black magnetic connector on the device side, and a button on the USB side . The Charge 4 charger doesnt work with FB422. To charge FB422:

1. Plug the charging cable into the USB port on your computer, or a UL-certified USB wall charger, or another low-energy charging device. 2. Attach the other end of the charging cable to the back of FB422. The pins on the charging clip must lock securely with the gold contacts on the back of the tracker. FB422 vibrates, and a battery icon appears on the screen. Charging fully takes about 1-2 hours. While the tracker charges, you can tap on the screen to check the battery level.

Wear FB422 Place FB422 around your wrist. If you need to attach a different size band, or if you purchased another band, see the instructions in "Change the band" on page 12. Placement for all-day wear vs. exercise When you're not exercising, wear FB422 a finger's width above your wrist bone. For optimized heart-rate tracking while exercising:

During a workout, experiment with wearing your tracker higher on your wrist (2 finger widths) 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 youre 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 FB422 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 FB422 on your dominant hand, change the Wrist setting in the Fitbit app:

From the Today tab

> Dominant. in the Fitbit app, tap your profile picture > FB422 tile > Wrist 11 Change the band FB422 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 35. Charge 3 bands are compatible with FB422. Remove a band 1. Turn over FB422 and find the band latches. 2. To release the latch, press the latch outward toward the band. 3. Gently pull the band away from the tracker to release it. 4. Repeat on the other side. Attach a new band To attach a new band, press it into the end of the tracker until you feel it snap into place and see the latch close into the locked position against the device body. If you have trouble attaching the band or if it feels loose, gently move the band back and forth to make sure it's attached to the tracker. 2020 Fitbit, Inc. All rights reserved.
