• Remove the Light engine air filter and fan pack to access the blue convergence adjustment screws. For
details, refer to
page 5-14. NOTE: Cooling is greatly affected by removing the filter and fan pack assembly.
You do not always have to turn the screws simultaneously; however, adjusting one at a time will cause the
need for an equal or equal and opposite turn on the other to prevent binding and achieve the adjustment
desired.
It is a good idea to locate the shorter blade 2.5mm driver on adjusting screw #2 (especially on the red), and use
the longer blade 2.5mm driver for screw#1 and horizontal (screw #3).
