3. Operation

3.1 Overview

The High Speed Shutter (subsequently referred to as HSS) virtually eliminates the shutter lag
associated with all modern DSLR cameras. While it may be used stand-alone it was designed to
work in conjunction with StopShot. StopShot's significant selection of sensor technologies
coupled with its incredible flexibility brings your photography to the next level with the HSS.
The simple to use single-button interface provides manual control while the two RCA
connections allow a complete interface with StopShot and your flash.
The included mounting hole plugs should be inserted into the unused mounting holes to prevent
debris from entering the shutter housing.

3.2 Manual Button

To manually active the shutter, press and hold the manual button for two seconds. The shutter
will activate at which point you can release the button. See below:

A single press of the manual button will cause the shutter to remain open. This is useful for
focusing your lens. The LED will turn orange indicating the shutter is open. When you complete
focusing press the button again to close the shutter.

NOTE: The shutter will not activate by button press or the "Trigger Input" while it remains in
