When a software update is available, your Fusion will automatically start downloading it the next time it syncs with the app. Your Fusion will need enough battery to complete the update, so it's always a good idea to have the device plugged into the charging cradle before you attempt the update.
Make sure your phone/tablet is connected to a reliable internet connection as well.
If your update is having trouble completing, it is possible that your Fusion has some stray files saved on it, causing the update to stall. But not to worry! There are a few things you can do to reformat your Fusion to successfully accept the update.
First, force quit the app and do a factory reset on your Fusion (instructions below). Make sure you have synced your current steps with the app, otherwise you will lose your current progress. You will then need to re-pair your device with the app. Once you do that, you should see the update prompt.
Factory reset: Double tap the Fusion to turn on the screen, then swipe to the left of the time/date (and battery percentage) screen to select Apps > swipe to the second Apps screen to select settings > swipe to the factory reset screen and tap the check mark to confirm.
If factory resetting the Fusion doesn't allow the update to go through, shoot us an email at email@example.com.
