READY-LIGHT INDI CATION
After the power supp ly is switched on, a red LED ready-light, built into the top of the lens barrel, lights up as soon as the ringlight is ready to fire. When the shot is taken, the ready-light goes out, but then comes back on as soon as the ringlight is recycled and ready to fire again. In addition, with the OAT A button on, the reproduction ratio visible inside the viewfinder serves as a ready-light. Thus, you can take pictures with any Nikon or Nikkormat camera without removing your eye from the viewfinder.
If the Medical-Nikkor is used in conjunction with the SC-22 sync cord and the Nikon F3-series (via AS-4 or AS-7), FA, FE2, FE, FM2, F-301jN2000, FG, FG-20, or EM (see t he previous section, "Connecting the Sync Cord"), the ready-light inside the camera's viewfinder operates, too.
