By default, all modules work in normal resolution. If you want to use coarse adjustment function you need to zoom out: hold the switch in (-) position and turn the control then. For fine adjustment you need to zoom in with the switch in (+) position.
The zoom module is connected internally to the Zero series module. If you have a number of mongo modules you still need one Zoom module only - connect the other zero modules internally with each other with the small jumper cables.
