1-2-8. C Board Removal (LDU-1515) 1 Rivet 2 Guard, PWB C 3 C board Note : All LEDs are installed in the holes of louver assembly. Lift up the C board egually not giving an excessive force, and remove it. Remove the C board to be replaced only.
1-2-9. LDU-1540S/1540L Exterior View LDU-1540S/1540L Rear View Front View Note : On replacing one of the units in the module, each unit is placed in each shelf; the top, the middle and the bottom. In three units, the top one and the bottom one cannot be replaced immediately because the module frame obstructs them.
1-3. Cleaning the Display surface 1-3-1. Criteria for display surface cleaning 1. Normally, clean the display surface once a year. However, in areas where the unit is liable to become dirty, clean the display surface by criterion 2. 2. When the difference in luminance between when the display surface is dirty and when the display surface is cleaned is 15% or more, clean the display surface.
