Loud fan noise
- When [High Altitude Mode] is set to [Level 2] or [Level 1], the fan noise becomes slightly louder since the fan rotation speed increases.
- Make sure that the room temperature is not too high.
- Check the installation requirements of the projector. Fan rotation speed increases to maintain the product reliability of the projector’s components in a room where the temperature is higher than normal temperature. The fan noise becomes louder in the room. The approximate normal temperature for the unit is 25°C (77°F).
