[Note] If no action is taken for approximately 10 seconds after LD-ON, it will become LO-OFF automatically.
If F close is selected during LD-OFF, it will become an error.
During focus search (S character measurement mode), too, safety regulation applies if LD_OFF is not selected
within 10 seconds. Therefore, even if focus search is selected after LD-ON, it will become LD-OFF after 9 seconds.
In order to F close after focus search (S character measurement mode), set to Power_OFF first then power on again
before F close.
