• Flashes with reversed polarity (the center contact on the hot shoe is minus)
cannot be used due to the risk of damaging the camera and/or flash.
• Do not combine with accessories that have a different number of contacts,
such as a Hot Shoe Grip, as a malfunction may occur.
• Combining with flashes from other manufacturers may cause equipment
breakdown. We recommend using the AF540FGZ, AF360FGZ or AF200FG.
