-CONTROLS IN DETAIL-continued----------
Sensor Unit SU-2 CD
The plug -in Sensor Unit SU-2 controls the operation of the SB-ll Speedlight. It has five settings to choose from.
At the Auto Positions
To shoot on Auto, lift up and turn the knurled ring on the outside of the sensor to one of the three positions (orange, yellow, or blue) which are color-coded for use with the exposure calculator dial. At these settings, the SB-ll is able to vary its light output automatically to match the flash -to -subject distance.
At the S (Slave) Position
At this setting, the SB-ll emits a modulated burst of light which can trigger a second electronic flash. The remote flash unit is attached to the receiver portion of the optional
Modulite Remote Control Unit ML-l (which is set to Channel 2), while the SB - ll Speedlight acts as the transmitter.
At the M (Manual) Position
Set the SU-2 to the M setting and the SB-ll operates manually at its maximum light output regardless of the flash -to -subject distance. In this case, you have to calcu- late the exposure manually by referring to the exposure calculator dial. See page 17 for more information.
