When the monitor was turned on by pressing the power switch or shutter-release button, or by rotating the mode dial, after the camera had entered standby mode with the auto off function with the Welcome screen set to any option other than None (default setting), monitor display was completely black with only information displayed. Further, when the shutter-release button was pressed halfway with this monitor display, the view through the lens was displayed, but the display included a significant amount of noise. This issue has been resolved.
