Portrait Projection (Vertical Orientation) - NEC PA622U User Manual

Portrait projection (vertical orientation)

Portrait screens from a computer can be projected by installing the projec-
tor in a vertical orientation. All the screens such as the on-screen menu
will be rotated in an counter-clockwise direction.
The projector is equipped with a sensor to automatically detect the instal-
lation state.
When the projector is installed in a portrait configuration for the first time
with the lamp lit up, a caution message to indicate that the operating time
of the lamp may be shortened will be displayed.
This message will automatically disappear when the installation state of
the projector is returned to the original state.
Precautions during installation
• Please do not install the projector in a vertical orientation on top of the floor or table on its own. The air inlet may
be obstructed, resulting in the projector getting warm and the possibility of fire and malfunction occurring.
• For vertical installation, install the projector with the air inlet (filter) facing downwards. A stand for supporting
the projector needs to be made for this purpose. 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.
• Do not use the lens shift function when performing portrait projection. Use the position of the lens shift mecha-
nism in the center (lens center).
NOTE:
• The lamp replacement time (as a guide)* is about 2000 hours for portrait projection.
* Replacement time is not guaranteed.
• When installing in a portrait configuration for the first time, portrait projection cannot be used when the number of lamp hours
used shown under [INFO.] → [USAGE TIME] → [LAMP HOURS USED] in the on-screen menu exceeds 1900 hours.
• When the [FAN MODE] is set to a mode other than [AUTO], portrait projection cannot be used.
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. Maintain an opening of at least 310 × 170 mm so as not to obstruct the air inlet / filter of the projector.
2. Maintain a distance of at least 130 mm between the projector air inlet and the floor (for the opening of the filter
cover).
3. 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.
4. Horizontal adjustment mechanism (for example, bolts and nuts in four locations)
5. Please design the stand such that it does not topple over easily.
