Cautions when transporting

・The projection lens (optional) is susceptible to effects due to vibration or impact.

  Make sure to remove the lens when transporting.
・When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impacts.

  They may damage the internal components and result in malfunctions.
・Do not transport the projector with the adjustable feet extended.

  Doing so may damage the adjustable feet.

■

Do not set up the projector in the following locations.

・Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal

  components or malfunction.
・Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases

  due to the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector

  or other equipment, or the air from the air conditioner does not blow toward the front of the projector.
・Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life

  of the lamp, or result in deformation of the outer case due to heat, which may cause malfunctions.

  The operating environment temperature of the projector should be between 0 °C (32 °F) and 45 °C (113 °F) when

  using it at elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 40 °C (104 °F) when

  using it at high altitudes (1 400 m (4 593') or higher – lower than 2 700 m (8 858') above sea level).

  If you use the Smoke cut filter, the operating environment temperature should be between 0 °C (32 °F) and

  35 °C (95 °F). However, it cannot be used at high altitudes.

  If you use the Replacement lamp unit (for portrait mode), the operating environment temperature should be between

  0 °C (32 °F) and 40 °C (104 °F) when using the projector at elevations lower than 1 400 m (4 593') above sea level, 

  and between 0 °C (32 °F) and 35 °C (95 °F) when using the projector at high altitudes. If you use the Smoke cut filter

  together, the operating environment temperature should be between 0 °C (32 °F) and 30 °C (86 °F).
・Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
・Places where there is high-power laser equipment: Directing a laser beam onto the lens surface causes damage

  to the DLP chips.

Note at the time of installation

・The high clarity projection lens is thermally affected by the light from the light source, making the focus unstable in
  the period just after switching on the power. Wait at least 30 minutes with the image projected before adjusting

  the lens focus.
・Make sure to set [HIGH ALTITUDE MODE] to [ON] when using the projector at elevations between 1 400 m (4 593')

  or higher and lower than 2 700 m (8 858') above sea level.

  Do not install the projector at elevations of 2 700 m (8 858') or higher above sea level.
・Do not use the projector tilted to the right or left.
・When installing and using the projector at an angle that exceeds 30° vertically, set [COOLING CONDITION].
・When using the portrait mode only lamp unit, install the projector with the terminals surface facing down.
