INSTALLATION AND ASSEMBLY
(10) Lighting
¶
Although reflection by external light as seen on CRTs will not occur with this projection screen, reflection may
result when strong light such as spot light is directed at the screen. Therefore, make sure that the screens are
not exposed to direct spotlight.
¶
For certain installation location conditions, a glass sheet may have to be attached to the screen surface. In this
case, as there will be reflection by external light, consider the installation position, etc. carefully.
¶
As the actual intended images of the system may not be obtained in very bright locations, consider the posi-
tion of lighting and direction of sunlight when installing the system. Especially when the system is exposed to
direct light (sunlight, etc.) from behind, the light may be reflected on the screen. Avoid such installations.
¶
Take note that in bright places, images may appear dark even when the luminance has been increased. In
addition, increasing the luminance and contrast more than required may affect the life of the system (espe-
cially the CRT).
(11) Effects of Earth Magnetism
¶
Due to effects of earth magnetism, the position of the image displayed will differ according to the installed
direction. Difference is about several mm in the up/down/left/right directions, but the degree of change varies
according to the strength of the earth magnetism of each area. Misconvergence may also occur due to slight
rotations.
Therefore, when performing adjustments before bringing the system into the installing location. Perform the
adjustments in the same direction and angle as installation, perform adjustments again at the final location
decided.
¶
If the system is used at a fixed position, adjust it at the final position used.
¶
The system is not only affected by earth magnetism but by the following magnetisms generated by various
items in its surrounding as well.
• Steel frame of building
• Power cables on the floor
• Large speaker systems
• Special equipment (Those generating magnetic force)
• Metallic installation table, frames, etc.
