• 
High Altitude
Use this function to control the cooling fan of the projector� You can set it to OFF or ON, 
the default setting is OFF�
Normally, the projector can operate normally when this function is set to OFF� The 
projector detects ambient temperature by default to regulate the cooling fan speed� 
When the temperature rises, the cooling fan speeds up (with higher noise) to exhaust 
the internal heat energy out of the projector and ensure its normal operation� However, 
the projector may turn off automatically if it is used in an environment at excessively 
high temperature or in an area at a high altitude� In this case, you can enable this 
function by setting it to ON and have the cooling fan operate at a higher speed to 
control the internal temperature of the projector�
Note:
•  The area at a high altitude means the place at an altitude of more than 5000 feet.
• 
Custom Power Level
Use the ◄► function to select the Custom Power Level. The projector allows a custom 
power level equal to 100%~75% of the lamp power in the Normal mode� This function 
is available only when the lamp power is set to Custom Power Level� It cannot be 
selected (highlighted) in the Normal or ECO mode�
