UNIQUE ELECTRONIC CONTROL INPUT OPERATIONS
The following pages illustrate unique customer input operations performed at the control panel. The input operations
described are: Temperature Unit Selection Mode, Contrast Adjust Mode, Tone Adjust Mode, Showroom Mode,
Sabbath Mode, Manual Zone Disable and Manual Freezer Evaporator Defrost.
Temperature Units Selection Mode (Selecting Degrees Fahrenheit or Degrees Celsius Display)
The appliance is initially set to display temperatures in Fahrenheit temperature units of measure, indicated by the “F”
at the upper right of the temperature readings in the LCD. This can be changed so Celsius units of measure are dis-
played by initiating Temperature Units Selection Mode.
NOTE: Temperature Units Selection Mode must be initiated within the first (1) minute after switching the unit ON.
To convert Fahrenheit (°F) temperature units of measure to Celsius (°C) within the first minute after switching the
unit ON, press and hold the ALARM key and the POWER key simultaneously for five (5) seconds, then release the
keys (See Figure 3-13); a “c“ will appear at the upper right of the temperature readings in the LCD, indicating that
temperatures will now be displayed in Celsius units of measure. Please note that changing from Celsius tempera-
ture units of measure to Fahrenheit is the same procedure (See Figure 3-14).
NOTES:
• Do not
press and hold the POWER key first, that will simply switch the unit OFF.
• Temperature Units Selection Mode will end ten (10) seconds after the last key stroke, or the ALARM key can be
pressed to exit this mode before the ten (10) seconds has elapsed.
