The first display line shows the start value of the aperture, and the second line the value at the end of the ramp.

Press the SEL button for longer than 2 seconds. The T-stop value in the first display line flashes. The required value can now be set using the handwheel. Press the SEL button again to switch to the next digit. The first digits are confirmed, and the decimal is set to ‘0’ by pressing the SET button.

The values in the second display line can be set accordingly.

Press the MODE button to go to the next submenu. To define the values for the minimum and maximum shutter angle (if controlled by the WRC-1), use the SEL and SET buttons and the handwheel, as described above. The first display line shows the start value of the shutter angle, and the second line the value at the end of the ramp.

Press the MODE button to go to the next submenu. To define the values for the minimum and maximum camera speed, use the SEL and SET buttons and the handwheel.

The first display line shows the start value of the camera speed, and the second line the value at the end of the ramp.

If the defined values result in a constant exposure, the display shows ‘CONST LIGHT’ when the MODE button is pressed. If this reading is not shown, the exposure is altered during the ramp.
