High Altitude Mode - Dukane 9010 User Manual

High Altitude Mode

Use this function to control the projector's cooling fan. You can set it to Off or On. The default setting
is Off.
Under normal circumstances, the projector will operate normally with this function set to Off. By
default, the projector will detect the temperature of the surrounding environment to regulate the speed
of the cooling fan. When the ambient temperature rises, fan speed will increase (generates louder
noise) to make sure the heat inside the projector gets discharged and keep the projector working
normally.
However, if you were to operate the projector in environment of excessive heat or in areas of high
altitude, the projector may automatically shut down. When this happens, you can enable this function
by setting it to On to force the cooling fan to work at a higher speed to regulate the temperature inside
the projector.
‡ High altitude region refers to area with elevation over 1500 meters (4900 feet).
‡ When operating in normal altitude environments, the projector will adjust the cooling fan
according to the temperature of the working environment. When the temperature rises
above 30C, the projector will automatically increase fan speed.

working environment is over 25C.

Power
This function will not be available if you have set the lamp to Eco or Normal modes, you can only
adjust this setting when the lamp has been set to "Power". You can specify the lamp power in the
range of 78% ~ 100%. Generally speaking, the lower the power, the dimmer the image will be but the
lamp will have longer lifecycle. In contrast, the higher the power, the brighter the image will be at the
cost of shorter lamp lifecycle.
