The dongle storage cover
This projector has a cover on the bottom where you can store socalled “dongles” such as casting devices and digital media players.

The device that has been confirmed to be able to be stored is the Google Chromecast (3rd generation).

1. The storage compartment is on the bottom of the unit, so you will need to place the unit upside down.
2. Prepare a flat table that is large enough to place the projector on and work on. (It is recommended that there be a margin of 10cm in both length and width beyond the size of the projector.) You will be working on this table, so make sure it is strong enough.
3. Place a sheet of cloth or similar on the table that is larger than the projector to prevent scratches.
4. Turn off the power to the projector and unplug the power cable.

Also, unplug all connected signal cables.

5. Place the projector upside down on the sheet. The front of the

device is inclined, it may be unstable when placed on the sheet, so

please be careful.

6) Place the prepared spacer on the front of the projector. At this time, make sure that the projector does not tilt or the spacer does not fall out by applying force to the unit.
Note
Make sure that the bottom surface of the projector is not tilted when placed between the spacer. A dongle placed on the bottom may slip off and be damaged.
7) Hook your finger into the tab on the cover and push and lift in the direction of the arrow to remove the cover.
8) The cover can be removed by lifting it up and sliding it off.

Install two projectors side by side. It is recommended that at least 20% of the width of the projectors overlap.
When installing, adjust the projectors so that they are oriented squarely to the screen. Since this is an ultra-short-throw projector, even a slight tilt will not result in a rectangular screen.
It is relatively easy to adjust the position and tilt of the projector by attaching a piece of paper with a rectangle of the desired projection size drawn on it to the screen in advance and adjusting the position and tilt of the projector to match the rectangle.
Set [Screen] > [Multi Projection] > [Multi Projection] > [On] in the menu system.

Open [Screen] > [Multi Projection] > [Edge Blending]>[Pattern] to display the Blending Pattern on both projectors.
This Blending Pattern can be used to measure the width of the area where the images from the two projectors overlap. The image below shows the red frame of the projected image of the two projectors, where the scale displayed from the right projector overlaps the outer frame of the left projector. From this image, the position of the intersection of the scale and the outer frame is read. The distance between the small arrows is 50, and in this case the width of the overlapped area is 730.

The left projector’s scale is oriented in the opposite direction, allowing the overlap width to be measured in the same manner.
