Standard workflow for mixed fleets

  1. Log intake: model/serial, impedance, jack type, NVG hardware, reported issues.
  2. Stage fast wins: ear seals, liners, visor tracks/screws, strain reliefs.
  3. Comms verification: mic alignment, mic element health, continuity on cords, sidetone check.
  4. NVG fitment: secure battery mount & cable routing; confirm balance & clearance.
  5. Documentation: record parts replaced, torque/fit notes, and next-due checks.
