DOT SHAPE:

NOTE: Changing neck assembly position will affect corner convergence.

Normally, no adjustments are necessary for these systems. If for some 

reason the data is lost, use the following data:

Write the data from any non-vertically compressed mode, then use the 

CPY1 function (CXA2170D-4 Item 6) to copy the data to the vertical 

compressed modes. V-compressed data is identical to non-v-compressed 

data. Service personnel with a trained eye can adjust the DF or DQP 

registers to adjust DF phase (Item 7) or DQP phase (Item 8), respectively, 

to balance left and right focus. Refrain from adjusting more than 5 steps 

from table data below. Further adjustment indicates a circuit problem 

-- troubleshoot to cause. Be sure that Neck Assembly is in the proper 

location
