About the assembly of the JOG dial display
The JOG panel is not coloring to improve the visibility of the LCD. So, internal dust and dirt on the surface are easy to see.
Therefore, attention is required when replacing the parts inside the JOG dial (especially when replacing TFT LCD (DWX4228)).
If it gets dirty during work, please remove it before working. In addition, the LCD is performed calibration at the mass
production. Therefore, do the same when replacing.
