Has anyone had this problem? The flash unit will not turn off, or let me change the settings. The only way to turn it off, is to remove the
batteries, When I install the batteries,it comes on as soon as I close the battery door. It is currently in TTL, HSS, WL (wireless remote). I
can use it, it works fine, but I cannot change any of the setting, or turn it off, without removing the batteries.
Thanks for any suggestions.
