Smart Temperature Control
The projector automatically monitors the ambient temperature
(operating temperature range is 0°C to 40°C), projector
temperature, and color wheel temperature, and the projector's
fan speed is automatically adjusted based on the detected
temperature values.
- The projector has three brightness modes to choose
from when operating at a normal temperature. To adjust
the projector's brightness level, go to Settings > Image >
Brightness Mode.
- If the projector gets too hot, an overheating warning will
appear and the projector will automatically switch to low
brightness mode. Temperature and error warnings will be
displayed automatically whenever the temperature exceeds
its maximum range to inform you that the projector will be
automatically turned off.
