Self-Test Mode

The display incorporates a self-test mode composed of a 1x2 checkerboard
pattern that inverts every few seconds. The self-test mode is entered by
applying power to the display with the S signal static. The display remains in
this mode until two (2) low-to-high transitions of the S signal are detected. The
display then enters and remains in normal (user video driven) operation as
long as power is applied. To enter self-test mode again, the display must be
reset by cycling the VH power input.
