   The firmware update Ver. 1.02 from Ver.1.00 incorporates the following issues:

   • We identified the phenomena below, which could arise in rare instances when certain EF-X500 units are in stand-by mode and when a communication error occurs between the camera and this flash unit.

   The phenomena below could occur in the aforementioned instances:

   1. The applicable EF-X500 flash unit does not properly respond to turn on from stand-by mode.
   2. The alkaline batteries may bec​ome increasingly hot. If you try to take the batteries out of the EF-X500 flash unit without turning the flash off and/or disconnecting the flash unit from the camera and letting the batteries cool down, a skin burn could occur.

   A firmware update is now available to address and prevent this potential occurrence in relevant EF-X500 units.
