If On is selected, a beep will sound when the camera focuses in
single-servo AF (AF-S or when shooting stationary subjects in
AF-A focus mode), when focus locks in live view, and while the
release timer is counting down in self-timer mode (0 54, 55).
The beep will not sound when Off is selected. In quiet shutter
release mode (mode J; 0 5, 53), this option is not available and
a beep will not sound when the camera focuses.
The current setting is shown in the information display: 3 is
displayed when the beep is on, 2 when it is off.
Choose On to use the exposure indicator to determine whether the camera is
correctly focused in manual focus mode (0 62; note that this function is not available
in shooting mode M, when the exposure indicator instead shows whether the subject
is correctly exposed).
