2.7 	Setting the Lens and using Lens Memories
Adjust the picture position
The  optimum  image  can  be  obtained  when  the  centre  of  this  projector’s  lens  and  the  screen  are  placed 
perpendicular to each other. Take note of the projection angle when placing them. You can also use up to +/- 15° 
up and down position and configure trapezoidal correction.
Screen Height(H)
Screen Base(H)
Horizontal Shift 
+/- 34%
Vertical Shift +/- 80%
This unit comes with a vertical and horizontal shift to suit most installations. Make sure that your installation 
does not exceed 80% vertical offset and 34% horizontal offset to avoid trapezoidal correction.
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:

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.
