ATL Ultramark 9 (UM9)

For the ATL Ultramark 9 (UM9) we catalogue 8 probe and guide references. Each model page covers what fails on that design and what a quote requires. Most of these come from ATL and Philips. The mix runs to convex, phased-array and endocavity, and failure patterns follow the design — lens delamination across the curved window shows up most on this kind of head. Send the full probe label photo along with the console model — revision differences matter for the assessment.
