device to charge normally.
When the ambient temperature is too high (above 60 degrees Celsius), the red high temperature warning
light will flash. Please move the device to a location with a suitable temperature (-10 degrees Celsius to 60
degrees Celsius) for the device to function normally. When the ambient temperature is above 45 degrees
Celsius while the device is being charged, the red high temperature warning light will flash as well. Please
