Formula for calculating possible heights when using the ET-DLE030
If using a screen size which has not been previously mentioned, use the following calculation formulas to
obtain the possible setting-up height.
For screen aspect ratio of 16:10
For screen aspect ratio of 16:9
For screen aspect ratio of 4:3
* There may be a small margin of error in the values obtained from the above formulas.
Shift range
Optical axis shift function allows to shift the position of a projected image as shown below.
• Floor mount
(When the lens except the ET-DLE085 and ET-DLE105 is mounted.)

Possible setting-up height A1 (mm) = Projection screen size (inches) x 5.0-72.1
Possible setting-up height A2 (mm) = A1 + 200
Possible setting-up height A1 (mm) = Projection screen size (inches) x 5.9-72.1
Possible setting-up height A2 (mm) = A1 + 200
Possible setting-up height A1 (mm) = Projection screen size (inches) x 5.7-72.1
Possible setting-up height A2 (mm) = A1 + 200
