Sensor Unit SU-2 8)
The Sensor Unit SU-2 controls the operation of the SB-14. It has five settings to choose from.
At the Three 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-14 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-14 emits a modulated burst of light which can trigger a second electronic flash. The remote flash unit is connected to the receiver portion of the optional Modulite Remote Control Unit ML-l (which is set to channel 2), while the Speedlight SB-14 acts as the transmitter.
Note: Although the 5B-14 operotes with maximum light output at the 5 position, be sure to set the camero's shutter speed dial at slower than the ordinary synchronization speed. For example, if the camero's synchro- nization speed is 1/125 sec., set the shutter speed at 1/60 sec . or slower.
At the M (Manual) Position
Set the SU-2 to the M setting and the SB-14 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.
Detaching the Sensor Unit
To detach the SU-2, push in the two protrusions at the base of the sensor and pull it out.
