The temperature around the machine is too high. Adjust the room temperature.

The internal temperature of the machine has risen above that at which it can operate.

This message appears when the temperature rises to 35°C (95°F) or higher during startup or operation (when recovering from sleep mode).

Bring the installed location to a temperature at which operation is possible (20 to 30°C [68 to 86°F]) and allow the machine to come to room temperature.
