<p>Check page 93 of the SU-800 manual. It looks to me like you can use it to control compatible flashes and cameras in Commander mode (not Close-up). It says to hold down the SEL button for 2 seconds to change to repeating flash mode. I tried it, and that works, although I didn't try taking photos...</p>
