My i-Beacon is open, how can I close it?

I have an open iBeacon and I'm having trouble reassembling it.  Can you help?

Reassembling the case

Reassembling the case

1. Place the board assembly (and battery) into the molded container.

2. Observe the tabs on the bottom cover one has a single tab, the opposite side a double tab.

3. There are matching slots in the top cover to align with the tabs.

4. Note, the side that accepts the double tab is the ONLY side that has a divider in the middle.  This divider will prevent anything BUT the double tab from fitting.

5. Don't forget the foam cushion when reassembling the case.
