1D00 0000
LD-OFF : 1000 0000
[Note] LD-OFF automatically occurs if no action is taken for approx. 10 seconds after LD-ON.
An error occurs if F close is attempted in the LD-OFF status.
Even during the focus search (S-shape measurement mode), failure of LD-OFF within 10 seconds violates
safety regulations. Therefore, LD-OFF occurs in 9 seconds despite focus search after LD-ON.
For F close after the focus search (S-shape measurement mode), power OFF first, then power ON again
