    You mean P-TTL, M, A and SB?

    M = you manually set the level of flash power output

    A = 'auto' thyristor mode, doesn't communicate with the camera like P-TTL does, instead you set the ISO and aperture and the flash adjusts power output based on the scene brightness

    SB = only use the AF assist lamp on the flash.

    IMHO A-mode is more reliable. P-TTL tend to meter under by 1-2 stops especially when the flash gets reflected somewhere in the scene. Also there is no pre-flashing in A-mode so you don't get shots with sleepy half-closed eyes among people whose eyes are more sensitive.

    PP is only useful if you have the TR-3 external power pack

    PH 1/2 enables/disables auto power off after x minutes
