Basic Operation, Main Switch, Shutter Button | Canon EOS-3 instruction

1. Basic Operation

Main Switch

The camera operates only after the < > switch is turned on. This main switch has three settings:

< >: Lock position. The camera does not operate. Set to this position when not using the camera.

< >: To turn on the camera, set to this position. The “A” stands for “Advance.”

< >: This is the same as < > except that it also enables the beeper to sound in the following cases:

• Focus is achieved in One-Shot AF mode.

• Focus is achieved with manual focus.

• During Eye-Control calibration. (Short beeps for successful registration and intermittent beeping for failed registration.)

When the camera is not to be used, set the Command Dial to < >. This will prevent accidental battery drainage if the shutter button is held down inadvertently.

Shutter Button

You can press the shutter button halfway or all the way.

Hold the camera steadily and press the shutter button slowly without any jerking movement. The difference between halfway and complete pressing of the shutter button is explained below. Beginners should practice pressing the shutter button halfway and completely before loading any film.
