Disconnect a ribbon from a connector behind the on/off button.
Gently lift off 2 snap-on connectors on the left hand side next to the lens assembly. (Two more at the top of the board can be left in place.)
You can now separate the logic assembly, battery compartment and top control panel as a unit from the lens and flash assembly. You will need to gently ease the red-eye LED out of its slot in the lens assembly.
