12 and 14 .
(GB) (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
B
Center of the screen
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
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)
to 158 .
