Notes
IMPORTANT: this is the coin-cell battery that powers the auto-darkening ADF lens electronics only — it is NOT the rechargeable PAPR blower battery. Do not confuse with the Miller PAPR blower packs already on file: Gen 1 blower battery 244131 or Gen 2 blower battery 287178. Those power the fan/motor; 217043 powers only the lens.
