On the bottom left hand side of the lens assembly there is a connector with a red and a black wire going to the speaker. Disconnect this, taking great care not to strain the wires or especially the ribbon that the socket is mounted on.

At the rear top left hand side of the lens assembly is a ribbon cable connecting it to the flash module. Disconnect this.

(Note the transparent protective insulation covering the flash board just below this connector. Do not remove this as the board may still have a dangerous high voltage on it from the flash capacitor behind.)

Remove a screw from the top right hand side of the flash module, and separate the flash module from the lens assembly.

(On reassembly, hold the flash head closed while refitting it to the lens assembly.)
