Since the ZM4 DAC output was close to saturation, I offloaded ZM4 yaw with SQZ ASC ON. The SQZ ASC seems to work and keeps good squeezing level. I reduced ZM4 yaw from -1408 to -1108 and the SQZ ASC moved ZM5 and ZM6. Then I offloaded AS42 ASC. I could reduce ZM4 yaw more, but lockloss happened. I accepted the attached SDF.
