Instruction manual

13. Aligning the lamp in
Aligning the lamp in the optical system is achieved via the 2 adjusters at the rear
lamp in the optical of the projector.
system This procedure should be undertaken to properly align the lamp in the optical
system and to avoid the possible overheating of the internal components due to the
incorrect focusing of the beam onto components not intended to be exposed to
this.
alignment procedure
Alignment is effected via the 2 adjusters A and B operating in conjunction with each
other. The lamp should be on and not dimmed, black-out fully open, and no colour
filters inserted.
If the lamp is not correctly aligned, a hot-spot will be noticeable. This is a function of
the lamp’s positioning. Use the two adjusters (A and B) to bring the hot-spot to the
centre of the beam and to flatten the beam to maximum uniformity.
vertical adjustment
Adjuster (B) acts on a lever and spring assembly to position the lamp via a vertical
movement within the reflector; rotate it until correct positioning is achieved.
horizontal adjustment
Adjuster (A) acts on a lever and spring assembly to position the lamp via a horizontal
movement within the reflector; rotate it until correct positioning is achieved.
