High Altitude
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 pro-
jector 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.
Note:
High altitude region refers to area with elevation over 5000 feet.
