Note:
Because there is a slight lobe on the J9001, the J-9 circuit board connecting tool may
not become clamped in some cases. If this happens, use a file to gently file away the
lobe. If too much is filed away, pin (16) of J9001 will form an open circuit, and it will not
be possible to use [AGC. DET] of pin (16) of J9001 as the measurement point for 7.
