Fig. 11

Notes:

 1. Wedge A, B and C should be inserted following the sequence of 1, 2 and 3 shown in Fig. 11.
 2. The wedges should be set 120° apart from each other.
 3. Be certain that three wedges are firmly fixed and the Deflection Yoke is tightly clamped in place.

Otherwise the Deflection Yoke may shift its position and cause a loss of convergence and purity.
