Einleitung

Use this guide to remove the motherboard. There is soldering required, so if you need assistant please read this soldering technique page.

Remove the four 12mm phillips head #2 screws located along the outer edge of the white case.
Be careful! There are two small, easily-broken, plastic tabs at the bottom of the device keeping it together.
Once you remove the screws, pick the device up so that the grey label on the bottom of the device faces toward you.
With your thumbs on either side of the grey label, slowly push with both thumbs until the case pops open.
A small gap will open as the two tabs are released.
Do not pull the two halves apart yet. They are held together by the speaker wire.

Grip both sides of the top round part of the case and carefully open it like a clam. The bottom of the two halves are connected by the speaker wire. Do not separate by more than 1 centimeter.
Grip either side of the top round part of the case and carefully open the device to reveal all the hidden treasures inside!
Lay the device down, so that all the internal components are facing upwards.

Turn the device over again so you are looking at the internals.
The Zipconnect unit will lift out but will still be attached by a wire connected to the motherboard.
Remove the six 7mm Phillips #1 phillips screws attatching the Zipconnect unit to the motherboard wire and set the unit out of the way.

Disconnect the speaker wire from the motherboard by firmly griping the wires close to the connection with two fingers and pull the connector out.
Wiggling the connector back and forth as you pull will make removal easier.

Remove the two 11mm Phillips #1 screws attaching the small brown circuit board to the plastic outer case.
Also remove the four 11mm Phillips #1 screws attaching the motherboard to the plastic case.

Lift up on both the motherboard and brown circuit board which contains the light intensity dial.
Turn over the motherboard and remove the solder connecting the wide, flat, grey wire.
