BASIC INPUT OPERATIONS
The following pages describe the basic input operations performed at the control panel (switching unit ON and OFF,
adjusting temperature set-point, switching lighting system ON and OFF, and enabling and disabling the tempera-
ture/door alarm feature).
POWER
All units are shipped in the OFF Mode. When electricity is supplied to the appliance, a short power up is initiated
where the temperature units of measure (°F or °C) is displayed for one second, followed by the model code for five
seconds, then all components are switched OFF and the LED displays go blank. By pressing the POWER key, elec-
tricity is allowed past the control board to the rest of the unit, indicated by the lights energizing, the cooling functions
beginning and temperatures appearing in the LED display windows. (See Figure 2-5).
