Speedlite 600EX-RT: memory function

If you’re working with Speedlite flash and find you always set your remote Speedlites up in a similar way when working with multiple flashguns, then instead of manually making each of the settings – Radio Wireless, Group Mode, Group and so on – simply make the settings once and navigate to Menu 2 on the Slaves or Menu 3 on the Master unit. From here, press the Memory option and select 'Save'. All the settings on the flashgun will then be saved for instant recall later. To recall them, navigate to the same menu, select 'Memory' again and choose 'Load'.
