The test pattern illustrated above is speci
fi
cally designed for convergence purposes. The test pattern has three blue arrows num-
bered from 1 to 3 and three green arrows numbered from 4 to 6. These numbers and colors correspond to those of the control
knobs. Each knob is marked with an arrow which corresponds to the direction indicated on the screen.
Adjustment Range
Prevent damage to the system by limiting the amount/number of adjustment(s) made. Typically the convergence adjustments serve
to correct a convergence fault of a few pixels at the most. Any convergence fault beyond this is considered grossly abnormal and
likely indicates abuse or rough handling. However, in extreme cases correction of up to 10 pixels is possible.
C
AUTION
:
The system does have an end of travel in either direction, but using excessive force may cause
damage. Please handle gently.
Troubleshooting ’dead zone’ of control knob
In the rare event that a knob is loose in the perfect convergence position, it is preferable to continue translating the image away for
approximately 20 to 30 pixels (max 1 revolution of the knob(s)). Note that this is the only time we allow for extreme adjustment.
Thereafter, return the image back to the correct position. The knob should now have become tighter in the
fi
nal position and therefore
resist turning due to vibrations and such. Repeat the procedure if you feel the knob is still loose.
