Operating-panel and footswitch operation & switch-clearance checks — 1.46/1.47
Confirm the right and left operating-panel switches and the footswitch actually drive the couch top by watching four dedicated LEDs (item 1.46), then confirm every operating-panel switch key top clears its acrylic plate by 0.5 mm or more on all four sides (item 1.47) — periodic gantry inspection items 1.46 and 1.47.
Applies to
Aquilion 16 (TSX-101A)
Personnel
1 technician · Basic — observe up to four LEDs (two on the operating panel's own PWB, two on the KGTSM PWB) while operating the right/left operating-panel switches and the footswitch, then read a clearance gauge against a single 0.5 mm standard on all four sides of each switch key top. No electrical measurement beyond LED state, and no component replacement, is called out in source for either item. (Skill assessment derived from the procedure content — not an OEM-stated skill level.)
