Installation
When the Screen Size is not Mentioned in the Tables
You can calculate the installation measurements described below when
you use the screen whose size is not mentioned in the tables on pages
12
(GB)
and 14
(GB)
.
Check your installation conditions:
• Screen size to be used (S)
• Installation measurements at the end of the manual, ES and BS for
smaller screen size and EL and BL for larger screen size
See the tables on pages 153
(GB)
to 158
(GB)
.
Now you can calculate the installation measurements as follows:
E (mm) = ES + ((S – smaller screen size)
×
(EL – ES)
×
0.1)
B (mm) = BS + ((S – smaller screen size)
×
(BL – BS)
×
0.1) + 289
Example: when using 124-inch screen
According to the tables on page 154
(GB)
, the values E and B are as
follows:
ES = 3279, BS = 791 (As the smaller screen size is 120 inch.)
EL = 3570, BL = 861 (As the smaller screen size is 130 inch.)
Therefore,
E (mm) = 3279 + ((124 –120)
×
(3570 – 3279)
×
0.1) = 3395.4 (mm)
B (mm) = 791 + ((124 – 120)
×
(861 – 791)
×
0.1) + 289 = 1108 (mm)
