Setting up your scale  Before you begin    1. Set your scale on
a hard floor (not carpet) near your internet router to ensure it
can detect your Wi-Fi network.    2. If you have an ethernet
cable plugged into your computer, unplug it.    3. Get your
home’s Wi-Fi network password ready since you’ll need to enter
it during set up.  Get started  Fitbit’s set up software will
enable your scale to connect and sync on your home’s wireless
network. You will use this software anytime you move or need to
change your scale’s Wi-Fi network in the future.   If you're
using a smart phone now, or don't want to download the set up
tool, use the web based set up  If you see this, don't panic!
Mac OS X Snow Leopard inaccurately recognizes the Fitbit base
station as a "network interface." You don't have to do anything
to your Network Preferences, though.  Just click Cancel.
