What does it mean if the icon “--” is lit and flashing in the temperature display of my Summit Professional SPR316OS?

The icon “--” is lit and flashing in the temperature display because only temperatures within the range 0~99°F/-9~37°C for FF1532B / SPR316OS / SPR627OS / FF64B / FF64BSS and the range -49~99°F/- 45~37°C for SCFF1533B / SPFF51OS / SCFF53B / SCFF53BSS / SCFF52W can be displayed. If the temperature is not within this range, the icon “--” will be displayed instead. This is normal.
