Just to let everyone know that this problem is not in the manual but I discovered it accidently. Was shooting off camera flash this weekend at a beauty pageant. Had two Promaster 7500EDF's on stands using wireless trigger/remotes in manual mode. After 5 minutes of non-use the flashes go into standby mode which is ok because you can wake them up by pressing the shutter or trigger button. What is bad is after they wake up, they have reverted back to TTL, losing all your manual settings. I wrote to Promaster about it and all they said was, that is how the flashes are designed to operate. More for the general consumer using automatic functions rather than manual. If that is true then why even have a manual setting if it reverts back to TTL after 5 minutes of non-use.

Oh well, live and learn. Just bought my last Promaster.

If memory serves, I think the 7500 has a built-in optical slave, which is really the only way it's designed to be used off camera. And if memory serves, I believe it will stay on indefinitely in that mode.

Maybe not a practical solution for a beauty pageant, but the fact is they are consumer-grade units. There's a reason they're so much cheaper than OEM Canon units.

According to Promaster, they go into standby mode after 5 minutes no matter if it is optical or not, just the mere fact of them going into manual. Once in manual it goes into standby for 5 mins of non use no matter the connection. I mean there are other flashes out there in the same price range and grade that hold their manual settings when it goes into standby.So far the photogs I have been speaking and writing to, only Promaster loses it's manual settings after going into standby. I mean who in the world would be shooting with flash in manual every 5 mins during an event. Sounds like their engineers didn't ask photographers about what they were doing or testing it with professional shooters.
