Unsuitable Conditions
Do not use the projector under the following conditions.
Toppling the unit
Avoid using as the unit topples over on its side. It may cause malfunction.
Tilting the unit out of the range of the adjuster setting
Avoid using when the unit is tilted out of the range of the adjuster setting. Such installation may cause color shading or shorten excessively the lamp life.
Tilting the unit to the right or left
Avoid tilting the unit to an angle of 15°, and avoid installing the unit in any way other than placing on the floor or suspending from the ceiling. Such installation may cause color shading or shorten the lamp life excessively.
Blocking the ventilation holes
Avoid using something to cover over the ventilation holes (exhaust/intake); otherwise, the internal heat may build up.
For details on the ventilation holes (intake/ exhaust), see “Location and Function of Controls” on page 11.
Usage in High Altitude
When using the projector at an altitude of 1,500 m or higher, turn on “High Altitude Mode” in the INSTALL SETTING menu. Failing to set this mode when using the projector at high altitudes could have adverse effects, such as reducing
the reliability of certain components.
Note on carrying the projector
The unit is manufactured using high- precision technology. When transporting the unit stored in the soft case, do not drop the unit or subject it to shock, as this may cause damage. When storing the unit in the soft case, disconnect the AC power cord and all other connecting cables, and store the supplied accessories in a pocket of the soft case.
Note on the screen
When using a screen with an uneven surface, stripes pattern may rarely appear on the screen depending on the distance between the screen and the projector or the zooming magnifications. This is not a malfunction of the projector.
