1. Preparing your Actus for installation
Before installing the AC-380 or AC-381 make sure you have the correct
knob. The AC-380 is indicated by a white dot on the barrel. The AC-380
is used for the Actus-B. The AC-381 is indicated by a red dot on the
barrel. The AC-381 is used only on the front standard of Actus-DB II and
the Actus-G.
Before installing the AC-380 slide the telescopic rail fully backwards and
lock it in position. Shift the camera plate fully to the left and lock it in
position. Make sure the geared focus is placed in zero position. With the
Actus positioned like this the accessibility of the focus knob mounting
screw is optimal.
2. Removing the Focus knob
To remove the focus knob place the supplied 2mm Allen key in the
mounting hole and unscrew the focus knob fixation bolt. When the
fixation bolt is loosened slightly rotate the focus knob back and forth
while pulling it out to remove it from the Actus.
