Vidikron model 100t ユーザーズマニュアル

Vertical Lens Shift: The Vision 90t/100t zoom lenses (options 1, 2, 3, 4 and 6 in Table 3-3) 
provide up to 80% of downward vertical lens shift. For example, with a 96 x 54-inch (16:9) 
screen, you can shift the image up to 43.20 inches (1.10 meters) below the screen center. 
(Upward vertical lens shift is not possible. Vertical lens shift is not possible in either direction 
with lens option 5.)

Horizontal Lens Shift: The Vision 90t/100t zoom lenses (options 1, 2, 3, 4 and 6 in Table 3-3) 
allow up to 10% of horizontal lens shift in either direction (left or right). For example, with a 
96 x 54-inch (16:9) screen, you can shift the image up to 9.60 inches (24.38 cm) left or right of 
the screen center. (Horizontal lens shift is not possible with lens option 5.)

In rear screen applications where space behind the projector is limited, a mirror may be used 
to fold the optical path, as shown in Figure 3-5. The position of the projector and mirror must 
be accurately set. If you are considering this type of installation, contact your dealer for 
assistance.

Other considerations and tips that can help improve your installation:

• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away 

from heating and/or air conditioning vents. Changes in temperature may cause drifts in 
the projector circuitry, which may affect performance.

• Keep the projector away from devices that radiate electromagnetic energy such as motors 

and transformers. Common sources of these include slide projectors, speakers, power 
amplifiers and elevators.
