Replace the XC PWB backup battery
Replace the XC PWB's backup battery (AVY005-01) — a short swap, but one that wipes the If (filament current) calibration data and the board's clock, so it always ends with a [RESET] and a full If-adjustment re-run.
Applies to
Aquilion 16 (TSX-101A)
Personnel
1 technician · Basic — turn off power, swap a single battery (AVY005-01) at PWB location 3M, turn power back on, clear one expected error with a front-panel [RESET] press, then re-run the If (filament current) adjustment to restore the calibration data that the battery had been backing up. No torque values, meters, or specialized tools are called out for the battery swap itself; the real skill floor is set by the If-adjustment procedure that step 4 hands off to, not by this swap. (Skill assessment derived from procedure content — not an OEM-stated skill level.)
