To set up your Fitbit Aria Air, download the Fitbit app on your smartphone, create or log into your Fitbit account, and follow the in-app instructions to connect the scale via Bluetooth. Make sure your phone's Bluetooth is on and that you have an active internet connection during setup.
If your Fitbit Aria Air is not syncing, ensure that Bluetooth is enabled on your phone and that it is within range of the scale. Restart your phone and the Fitbit app, and try stepping on the scale again. If the issue persists, unpair the scale from the app and pair it again.
To change the weight unit on your Fitbit Aria Air, open the Fitbit app, tap on the profile icon, select Aria Air, and choose the desired weight unit (pounds, kilograms, or stones) under the 'Units' section.
Ensure that the scale is on a hard, flat surface and that you are standing still during measurement. Remove any obstacles from under the scale, and make sure your feet are positioned correctly on the sensors. If the issue persists, recalibrate the scale by stepping on and off until you see '0.0' displayed.
To add multiple users, each user must download the Fitbit app and set up the scale on their device. They need to log in with their Fitbit account and follow the setup process. The scale recognizes individual users by syncing data to the correct account based on the app connection.
The Fitbit Aria Air requires a smartphone for initial setup and syncing data. While the scale can display weight measurements without a phone, syncing and tracking historical data necessitate the use of the Fitbit app on a smartphone.
To replace the batteries in your Fitbit Aria Air, turn the scale over, open the battery compartment, and replace the old batteries with three new AAA batteries. Ensure the batteries are oriented correctly before closing the compartment.
If an error message appears, check that the scale is on a hard, flat surface and that your feet are clean and dry. Restart your scale by removing and reinstalling the batteries. If errors persist, consult the Fitbit help resources or contact Fitbit support for further assistance.
To clean your Fitbit Aria Air, use a soft, damp cloth to wipe the surface. Avoid using any harsh chemicals or submerging the scale in water. Ensure that the scale is dry before using it again. Regular cleaning helps maintain accuracy and prolongs the device's lifespan.
To view your weight trends, open the Fitbit app and navigate to the 'Today' tab. Tap on your weight card to see a graph of your weight over time. You can adjust the time frame to view daily, weekly, monthly, or yearly trends.
