If you are using an external meter you need only to set the desired aperture and shutter speed.
The aperture is continuous from f/2.8 to f/22 and is set using the inner portion of any of the lens barrels. There are detents provided at each stop and half-stop (thirteen in total) but the aperture really is continuous and can be set between the detents.
The shutter speed is set to one of ten values and is controlled by rotating the knob on the top right of the camera. The shutter is synched for electronic flash at speeds at and below 1/60th second. While the camera is marked with a synch-speed of 1/60th, I have successfully used 1/125th and suspect 1/250th would work at f/16 and f/22.
If you are using the built-in, TTL meter, frame your image and activate the meter. To do so, you may either half-press the shutter button or press the meter button on the left side of the camera. Depending on how you hold your camera, one of these should be easy to get to.
With the meter activated, one or two LEDs will be lit along the right side of
Actually exposing your film is as simple a pressing the very obvious shutter button located under your right index finger. The shutter button is threaded to accept a standard cable release. Next
