QUICK INSTALLATION GUIDE
PREPARATION ¨
Take the following 4 items into consideration when installing the projector .
1) Distance between the projector back and the wall (W1)
2) Heights: image width (height) (H1), height between the bottom of the image and the
desk (H2), height of the desk (H3), and the recommended height of the wall (H4)
3) Surface for placing the projector You can place the projector on almost any sturdy, flat
and level surface (here a desk e.g.), to project an image. Dimensions of the desk: -
Mobile desk: W2, H3, and L2 - Immobile desk: W2, H3, L2 and W1 (need to leave enough
space to move the device on the desk)
4) Image of the projection The wall for the projection should be larger than the area of
your desired image size. Wall area: length (L3, ≥L1) x width (H4, ≥H1 + H2 + H3) in the
diagram.

Take 100” image (Immobile desk) for example
1) Distance (W1): 18.2cm / 7.2in.
2) Heights: H1: 124.5cm / 49.0in; H2: 30.8cm / 12.1in; H3: 37.0cm / 14.6in (thus the image
center is at 1.3m / 51.2in high, suitable for audience sitting on a sofa in front); H4: 􀂜
192.3cm / 75.7in.
3) Area of the desk (L2 x W2): 􀂜53.3 x 55cm / 21.0 x 21.7in.
4) Area for the wall (L3 x H4): 􀂜221.4 x 192.3 cm / 87.2 x 75.7in.
1) Conversion figures may have been rounded up or down.
2) Leave plenty of space around and under the projector for ventilation, and keep the
vents unblocked in all directions.
3) Position the projector within reach of a grounded electrical outlet or extension cord.
4) The image size increases as the projector gets farther from the wall. Please move the
desk for placing the projector as the distance requires.
5) For H3, a recommended value is provided for a better experience since you would feel
it comfortable watching from the sofa when the image center is at 1.3m / 51.2in high.
You can change it as per actual needs.
