[FAN Set] On some occasions fan noise should be reduced to a minimum. Therefore you can set three different fan speed modes. • Press the ▲/▼ buttons until the desired function is showing on the display. • Press the [ENTER] button: the values can be changed • Use ▲/▼ buttons to select one of these options:[Auto]: the fan speed will be automatically adjusted to always have the best balance between fan noise and performance (light output). This is the best setting for use in theatres, conference rooms, … • [Low]: the fan speed will always be low to reduce fan noise to a minimum. However this means that the LED temperature could become too high: in that case the LED current will be reduced automatically to protect the LED. Light output will also be lower.[High]: the LED will be well cooled so maximum light output can be guaranteed under all conditions. However this means that fan noise will be higher than usual.
