Connection

When connecting a signal source to the projector, be sure to:

1.Turn all equipment off before making any connections.

2.Use the correct signal cables for each source.

3.Ensure the cables are firmly inserted.

•In the connections shown below, some cables may not be included with the projector (see "Shipping contents" on page 6). They are commercially available from electronics stores.

•This projector has no speaker or built-in support for audio reproduction.

Connecting a computer

The projector provides a VGA input socket that allows you to connect it to a notebook or desktop computer.

Additionally, you can also connect the projector to a computer via the USB cable so you can perform paging operations of the application on the PC or notebook. (see "Remote paging operations" on page 27).

The projector can also be connected to a computer via wireless connection. See "Using the wireless functions" on page 28 for details.

To connect the projector to a notebook or desktop computer:

1.Take the supplied VGA cable and connect one end to the D-Sub output socket of the computer.

2.Connect the other end of the VGA cable to the D-SUB/COMP IN signal input socket on the projector.

3.If you wish to use the remote paging function (see "Remote paging operations" on

page 27), take the supplied USB cable and connect the larger end to the USB port of

the computer, and the smaller end to the USB socket on the projector. The final connection path should be like that shown in the following diagram:

•A Mac adapter (an optional accessory) is needed if you are connecting legacy version (www.apple.com/usen/legacy/legacy_list.html) Macintosh computers.

•Many notebook computers do not turn on their external video ports when connected to a projector. Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/LCD or a function key with a monitor symbol on the notebook computer. Press FN and the labeled function key simultaneously. Refer to your notebook computer’s documentation to find your notebook computer’s key combination.

•For information about how to connect the projector to a computer wirelessly, refer to "Using the wireless functions" on page 28.
