Kodak Ektapro Slide Projector 4020 - Manual (Page 51)

Focus
There are different possibilities to get a crisp and clear focused image on the screen.
1. Use the FOCUS KNOB. In this case the LENS will be moved inside the LENS CARRIER, while the LENS
CARRIER still keeps his position.
2. Use the FOCUSING BUTTONS either on the KEYBOARD of the PROJECTOR or on the REMOTE
CONTROL. In this case the LENS and the LENS CARRIER are moving together. The focus range
is limited, and depend on the ECCENTRIC of the FOCUS MOTOR (approx. 8mm / 0.3 in.).
