G2 ADJUSTMENT
Once the on-screen menu "G2 ADJUSTMENT" is displayed, proceed
as follows :
remove the top cover from the projector (see p.4-1) and open the
front metal protection cover by turning out the 3 retaining screws on
both sides.
A green LED is mounted on each of these amplifiers.
When selecting the G2 adjustment menu, these green LEDs must
be out. If not, follow the next procedure to adjust the G2 :
open the second metal cover by turning out the retaining screws
on both sides and pivot the cover to the front side of the projector;
adjust the G2 potentiometers very slowly with a screwdriver until
the LED of the corresponding amplifier just stops illuminating.
Repeat the adjustment for the other colours;
once the three G2 potentiometers have been correctly adjusted,
close both metal covers and secure with the retaining screws.
After finishing the adjustments :
Press ENTER to continue with the "SERVICE" menu.
Press EXIT to return to the "SERVICE" menu.
Press ADJUST to return to Operational mode.
