Unscrew the two screws (D) on the left and right of the
front panel. Unscrew the three screws (E) on the bottom
and take the panel off. The position of the screws is shown
by the arrows in Fig. 42.
The distance between the projector and the screen
(depending on screen dimensions), is shown in the
following table.
TABLE 1: FRONT PROJECTION
A = Distance between the front panel and the screen
B = Distance between the projector’s desktop line and
screen centre.

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.
