Setting Up the Camera Using an RM-P2580

When the difference in brightness between objects is large, the picture may not change
even when the ExDR LEVEL is varied. This is due to the characteristics of the camera
and is not a malfunction.
●
When the item “SHUTTER” is set to 1/250 or higher, “---“ is displayed and the settings to
the item “ExDR LEVEL” cannot be carried out.
●
When the item “ExDR MODE” is set to OFF, the settings for the item “ExDR LEVEL”
cannot be varied.
MEMO
This function sets which section of the object is to be displayed in the easiest-to-
view brightness level in the ExDR mode.
To make a low-light section of the object easy to view: Increase the level.
To make a highlighted section of the object easy to view: Decrease the level.

frequency is 50 Hz. 2) The shutter speed is set at 1/50 in areas where the commercial
