Since I have an su800, I use my speedlights in remote mode. According to page 21 of the SB800 Instruction Manual, "the standby function does not work regardless of the SB-800's setting when the Speedlight is used as a remote flash unit." But one of my sb800s goes into standby mode after a few minutes of inactivity, the other doesn't, and I can't find any difference in their settings. Someone told me to take the sb800 out of remote mode, change the standby setting to "---", and then put the sb800 back in remote mode. It was a good plan, but it doesn't work. Any ideas? Or do I just have a bad Speedlight?
