The projector can be positioned manually varying the inclination. To do
this, loosen the fastening knob (see 4 in figure 2) and position it by holding the
back plastic handle (see 8 in figure 2).
Be careful not to touch the metal parts because the focus can reach high
temperatures.
To fix it again, turn the fastening knob clockwise until fixed it.

4.1. Aperture angle adjustment

The spotlight angle, and consequently the diameter of the light beam can
be changed by turning to right and left the focal adjustment nut (see 9 in figure
