If the temperature reaches 260F (127C), along with the above indications, the bar graph will flash. Once this condition is
reached, the buzzers can no longer be canceled by pressing the OK button (Figure 52, Item 5). When the oil temperature drops
below 248F (120C), the warning light (Figure 52, Item 31) will be automatically extinguished.
