IDK whom it concerns. - We got a letter that various models might have 220V on the wire around the flash tube and might be dangerous that way and are ordered to send them in for a free fix that will take aproximately 2.5weeks. FTR: German domestic wiring is indifferent about which cable will be hot or cold in a wall socket (unlike in the UK where roles are clear due to plug shape). in doubt contact your dealership or make disconnecting the flash to change reflectors a habit or measure if there is Voltage. - Be better safe than sorry!
