Camera User Setting

This entry, the first in the third Set-up menu tab, allows you to register your EOS 40D’s current camera shooting settings and file them away in the C1, C2, or C3 positions on the Mode Dial. Doing this overwrites any settings previously stored at that Camera User position. You can also clear the settings for any of the three Mode Dial positions individually, returning them to their factory default values.
