1. Apply power to the case. Wait for the self check
to complete. During the self check, each LED
flashes for 1 second, and then all LEDs turn on
for 2 seconds. If the LEDs do not flash, make
sure the adjustment knob is not in the "OFF"
position. The display will also be blank "OFF."
Upon power up, the display will show the case
temperature. The initial defrost will occur 2
hours later. The display will show the "DF" at
initiation of defrost. This reading will remain
displayed during defrost and until it times out,
even though the refrigeration mode has been
initiated. (The green LED will be on.) The sub-
sequent defrost will occur at 6-hour intervals,
after initial defrost (4-defrost/day).
