in Fahrenheit and Celsius where xxxF is ºF and yyyC is ºC
d) Compare displayed temp with the digital thermometer reading. CAL TEMP should read within
±3ºF (±1ºC) of temperature on the digital thermometer. If temperatures are within 3ºF (1ºC) of
each other, proceed to Step f. If the difference between temperatures exceeds 3ºF (1ºC),
proceed with Step e.
e) Change the CAL TEMP to match the thermometer reading. Use the “2” button to increase
CAL TEMP and “8” button to decrease the CAL TEMP. Always increase or decrease CAL TEMP
in increments of 3 - 5 degrees, then wait about 1 minute for the oven to adjust. You may not see
an immediate change in CAL TEMP when “2” or *”8” is pressed. Repeat as necessary.
IMPORTANT: Pressing CANCEL at any time while in the TEMP CAL mode will cause any
changes to be ignored. These changes will neither be saved nor implemented.
