2.0 INSTALLATION GUIDELINES
R699820 - Yunzi Series User Manual 13
This unit comes with a optical shift that features vertical and horizontal adjustment of the projection screen position.
Adjust the picture to your screen.
• The Vertical Shift level is between -80% and 80% of the Screen Height (0.80 x H).
• The Horizontal Shift level is between -34% and 34% of the Screen Base (0.34 x B).
•If the projector is not installed perpendicularly to the screen, use keystone correction to fulfill your screen. Note
that using keystone correction, may be disabled by 3D projection. If you want the best possible 3D pictures, It is
not recommended to use trapezoidal correction.
•If you plan to use the vertical and horizontal shifts without keystone correction, make sure to not exceed the
values contained in the tab below:
2.10.0.1 Adjust the picture position
The Yunzi Series projector has motorized vertical and horizontal shifts. Browse into the Menu to the [Lens Control]
setting into the Installation menu, select the shift adjustment. Or use the direct access button on the Remote Control
Unit [Lens Control] to make the lens adjustment.
You can use self-generated test pattern of the projector or an external pattern, from a calibration DVD by example,
by setting the Adjust pattern option to Off.
2.10.0.2 Adjust the picture Zoom
Into the [Lens Control] menu, press the [Ok] button to access the Zoom adjustment. Use the up and down buttons to
adjust the picture size until the screen is completely filled.
2.10.0.3 Adjust the Picture Focus
From the [Lens Control] menu, press the [Ok] button to access the Focus adjustment. Use the up and down buttons
to adjust the picture focus
Using Lens Memories
You can save the current picture position, zoom and focus in up to 5 different Lens Memories (10 for Yunzi 2 & 3).
Each memory stores the current position, zoom, focus of the lens and you can also set a custom name of 10
characters or less.
•Saving current lens setup
Fist step is to set the lens to fill the desired screen. Then go into the Menu ⇒⇒
⇒⇒ Installation ⇒⇒
⇒⇒ Lens Control, Select
Lens Memory Save and choose a free slot available. You can call back anytime later this current lens setup using
the direct access button [Lens Mem]ory on the RCU.
• Limitations of use
Each memory can store a different picture size and position, but there are limitations on the possible pictures sizes
and positions because of the projector being at a fixed location. In order to calculate the best position of the
projector toward the screen, the installer has to make sure that among the different desired pictures, the smaller one
with the smaller zoom, is within the offset limits (horizontal and vertical shifts) of the projector. Once the position of
the projector is determined by the smallest possible picture, double check that the larger one does not exceed the
zoom capacity.
