A. Stopped-down-aperture metering
When, using FD lenses, the image in the viewfinder is always the one at the full aperture. This is because that this camera has built-in full-aperture meter.
And also, the stoppedo-down-aperture metering is prepared when needed.
Hold the camera to the subject and select either 1. shutter speed or 2. apeture value, and when focusing is done, pull down the lever in the direction of "A".
Then, set the rest of "1" or "2" and release the shutter.
B. Self-timer
Wind the film wind lever to charge the shutter and pull down the lever in the direction of "B".
Depress the shutter button and the shutter will be released in 10 sec.
