(14) Remove crystal filter bypass networks from between A4A7TP7 and A4A7TP8
(15) Adjust A4A7C15 (fig. 12) for minimum signal peak amplitude.
(16) Adjust A4A7C14 (fig. 12) for best symmetry of signal.
(17) Repeat (15) and (16) above to ensure signal is nulled and adjusted for best
symmetry.

(20) Adjust A4A7C23 (fig. 12) for best symmetry of signal.
(21) Repeat (19) and (20) above to ensure signal is nulled and adjusted for best
symmetry.
(22) Remove crystal filter bypass networks from between A4A7TP3 and A4A7TP4
(23) Adjust A4A7C33 (fig. 12) for minimum signal peak amplitude.
(24) Adjust A4A7C32 (fig. 12) for best symmetry of signal.
(25) Repeat (23) and (24) above to ensure signal is nulled and adjusted for best
symmetry.
