2-3-5-2. Operation and Display
The Self Check mode transits to this mode when [RIGHT] key is
entered. Only the first segment of each grid of FLD turns on, and
each time the SHUTTLE is entered, the segment of each grid is
switched in order. When SHUTTLE input is clockwise, the seg-
ment switches in 1 → 2 → 3 direction, or counterclockwise it
switches in 3 → 2 → 1 direction. This tests whether each segment
turns on individually.
