4.3.1 Installation choice
Choose one of the following possible installation types (see: Installation types, page 32):
∙DESK TOP FRONT PROJECTION
∙DESK TOP REAR PROJECTION
∙CEILING FRONT PROJECTION
∙CEILING REAR PROJECTION
Attention:
Correct use of the spacers, as shown in the spacer tables, is mandatory for a perfect focus uniformity. Check that the projector is perfectly stable.
SIM 2 MULTIMEDIA S.P.A. declines all responsibility for damages to persons or things caused by incorrect or careless ceiling installation which must be effected by a qualified technician.
4.3.2 Desk-top front projection
Attention:
The bottom of the projector must be parallel with the floor. It is very important to know the correct projection angle.

Note: For 16/9 screen formats, measure the width and
refer to the nearest width value in the table.
.
If the size of the screen diagonal is not given in the table, dimension A ( in cm) is determined as follows:
-Measure the screen diagonal and take the nearest value from the table.
-Calculate the ratio between the table value and the relative width.
-Multiply the value obtained by the actual screen width.
Example: Suppose we have a 105” screen diagonal. 100” is the nearest value in the table.
The A/Width ratio is equal to 294/203.2=1.446 A 105” screen diagonal is 213.3 wide.
So, the value of A is: 1.446x213.3=308.4 cm.
