The Self Check Mode transits to this mode when
The Self Check Mode transits to this mode when
R key is entered. This tests whether each grid turns on individually. The first grid only
of FLD turns on and other grid turn off. Each time the SHUTTLE is entered, the grid is switched in order. When SHUTTLE input is
clockwise, the grid switched in 1 - 2 - 3 direction, or counterclockwise it switches in 3 - 2 - 1 direction.
