The semi auto delay mode is available on FCU's that have firmware revision rE1.0 and higher. To program it, enter programing mode and scroll to the "Sr" menu. The default is Sr0F (off). If you press up on the joystick you will change it to Sr01 which is a 0.1 second delay in-between shots. You can continue to increase that number in 0.1 second increments up to Sr99 which is a 9.9 second delay in-between shots.
