What are the bits that ship with a zip?

What are the two parts that came with my zip? One looks like a usb connector and then the semicircular flat bit?

Welcome @beck2017 to the Forums! I'd love to help. This is what’s you’ll find in your Zip's box:

1. Fitbit Zip Wireless Activity Tracker
2. Clip
3. Battery door tool
4. Wireless sync dongle
5. 3V coin battery, CR2025

To insert the battery: 

1. Remove your Zip from its packaging and then use the battery door tool to unlock the battery door. Insert the tool into the slot on the back of the unit, and turn the door counterclockwise to remove it.
2. Once the door has been removed, insert the provided battery into the back of the unit, with the “+” sign facing up. The battery will rest in the center of the compartment.
3. Once the battery is in place, align the arrow on the battery door with the ‘unlock’ icon on your Zip to put the battery door in place. Use the battery door tool to ‘lock’ the battery door by turning it clockwise until the arrow on the door lines up with the ‘lock’ icon.

     4. Once the display comes on, you will be ready to proceed with setup. The device version of your              Zip will appear on the display, followed by a series of smiley faces, which are used to represent              your activity level. The display will remain on for 30 minutes after inserting the battery.

     5. Take the wireless sync dongle from the box and plug it into a USB port on your computer.

     6. You are now ready to get started with setup.

To set up your Zip to your Fitbit account can follow this setup guide. 

I hope this helps, keep me posted!
