HS on / off 
Press the “HS” key briefly: Turn the scrolling wheel up or down. HS mode switches on and off. Confirm the selection by a short press on key “HS”.

Menu "HSMA"
When HS is active, HSMA (HS Manual Adjust) improves the exposure to suit the camera model being used. The purpose of HSMA mode is to override the automatic HS flash trigger. The automatically calculated shutter release is cancelled. 

The delay of the flash trigger signal (HSMA) depends on the camera, and so is different from model to model. The transmitters are factory set to work correctly with most models of a given brand, however, if you should notice a black bar across the exposed image you should utilize the HSMA function to adjust the timing until the black bar is no longer visible in the exposed image.

Longer press on key "HS" for HSMA (HS Manual Adjust): turn the scrolling wheel up or down. In this way HSMA mode can be set individually. Confirm the selection by a short press on key “HS”.
