c4: Remote on Duration

Choose how long the camera will remain before cancelling the
currently selected remote control release mode and restoring
the previously selected release mode (0 37). Choose shorter
times for longer battery life.

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 39), when
focus locks in live view, while the release timer is counting down in self-timer and
delayed remote release modes (0 37), and when a photograph is taken in quick-
response remote mode (0 37). Select Off to prevent the beep from sounding. Note
that a beep will not sound in quiet-shutter release mode (mode J; 0 35).
The current setting is shown in the information display: 3 is
displayed when the beep is on, 2 when it is off.
