The approved environment temperature range for projector operation is 0~40 °C.
When the environment temperature is 25°C, the measured temperature of the plastic enclosure is around 29 to 32.1°C and around 46.5°C for the plastic outside of fan openings. According to regulatory compliance, it would be around 38 °C once the Electronics Control is turned on when the environment temperature is 25°C, and the projector is in AC standby mode.
Please refer to the user manual for the suggested temperature range for safe use.
