you to a chart. In all cases, the fault analysis charts present the logical sequence of checks and remedial procedures. These charts are divided into three parts :

-one, (CAMERAANALYSIS) for problem analysis when the camera is completely assembled

-two, (OPTICAL ANALYSIS) for analysis of the viewfinder parts

-three, (SHUTTER ANALYSIS) for detailed shutter analysis.

The SHUTTER ANALYSIS charts should be

used only after the shutter has been unsoldered from the camera. If repairs and/or replacements are indicated, the procedures are described in Section IV.
