The teardown shows a christmas tree Nano, but should you have a bigger - Classic one, you may follow these steps - upscaling everything.

First order of business: presents!

Use caution and joy when opening your presents.

Disconnect the power plug

Remove the power socket, should there be one on your tree.

To remove the baubles, lift them gently and untangle the string from the branch.

If you find a capacitor on your christmas tree, straighten its leads to detach it.

All discrete electronic elements should be removed in this manner.

Protective hand-wear may come in handy.

Remain gentle, even when an element is very difficult to untangle.

To remove the top ornament, lift it upwards.

Finally, remove the lights.

Begin with the light that was placed as the last. If you are uncertain, start from the topmost one.

Before you run around barefoot in celebration, clean up.

Check amongst the floor sweepings for any surface mount components components which may have gone missing during assembly, and carefully put them aside

The christmas tree is disassembled!
