Resetting factory settings
Perform this procedure if the display is abnormal or if operations cannot be performed.
Various settings are reset to the factory default values. Make settings again.
“Initialized” appears on the display.
If “Initialized” does not display in step 3, start over from step 1.
It takes approximately 90 seconds for all of the settings to be returned to the default settings. When turning the power off, do not remove the power plug for approximately 90 seconds after “Initialized” is displayed.
