② Check for a gap or significant height difference between modules.
※ If a gap is found: A black line is visible from all directions.
※ If a significant height difference is found: A white line is visible when viewed from one direction. When viewed from the opposite
direction, a black line is visible.
③ If a gap is found, move the modules with hands, beginning from the outer modules.
④ If a significant height difference is found, disassemble the lower LED modules and adjust the height
by turning the Holder-Magnet with an appropriate tool.
