Thermal Warning

Your Spectacles shouldn’t cause thermal discomfort during normal use. If they do, stop using them and allow them to cool down before using them again. 

Spectacles are designed to operate between 32 and 96F (0 and 35C). Do not use Spectacles if the temperature is outside this range. When your Spectacles are outside the operational range a warning will be shown before they either go to sleep or shut down.
