c4: Remote on Duration (ML-L3)

Choose how long the camera will wait for a signal from the
optional ML-L3 remote control before cancelling the currently
selected remote control release mode and restoring the
previously selected release mode (0 31). Choose shorter times
for longer battery life. This setting applies only during
viewfinder photography.

d: Shooting/Display

d1: Beep

Choose the pitch (High or Low) of the beep that sounds when the camera focuses
using single-servo AF (AF-S or when single-servo AF is selected for AF-A; 0 33), when
focus locks in live view, while the release timer is counting down in self-timer and
delayed remote modes (0 31), and when a photograph is taken in quick-response
remote mode (0 31). Select Off to prevent the beep from sounding. Note that a
beep will not sound in quiet-shutter release mode (mode J; 0 29).
The current setting is shown in the information display: 3 is
displayed when the beep is on, 2 when it is off.

reference when composing photographs (0 4).
