Portrait projection (vertical orientation)
Portrait screens from a computer can be projected by installing the projec-
tor in a vertical orientation. Angle to display all the screens such as the
on-screen menu can be changed by the menu [SETUP]

[MENU(2)]
→
[MENU ANGLE].
Precautions during installation
• Please do not install the projector in a vertical orientation on top of the floor or table on its own. The intake vent
may be obstructed, resulting in the projector getting warm and the possibility of fire and malfunction occurring.
• A stand for supporting the projector needs to be made for portrait projection and for installing the projector in
universal angle. In this case, the stand must be designed such that the center of gravity of the projector is located
well within the legs of the stand. If not, the projector may fall over and result in injury, damage and malfunction.
Design and manufacturing conditions for the stand
Please engage an installation service provider for the design and manufacture of the customized stand to be used for
portrait projection. Please ensure that the following are complied with when designing the stand.
1. Secure sufficient space between the projector and the floor:
* Installation facing the intake vent downward: 130 mm or greater.
Installation facing the exhaust vent downward: 200 mm or greater.
2. Use the four screw holes at the back of the projector to secure it to the stand.
Screw hole center dimension: 200 × 250 mm
Screw hole dimension on the projector: M4 with a maximum depth of 8 mm.
* Please design the stand such that the rear legs at the back of the projector do not contact the stand. The front
legs can be turned and removed.
3. Horizontal adjustment mechanism (for example, bolts and nuts in four locations)
4. Please design the stand such that it does not topple over easily.
