Using the Token Wizard
You can use the Wireless Connection 3 token wizard to copy Wireless Connection 3 to USB memory.
After you do that, you can run Wireless Connection 3 on a computer that does not have the program
installed simply by plugging the USB memory (called a “USB Token”) into the computer’s USB port.
Using USB tokens is recommended when connecting to the projector from multiple computers.
Installing Wireless Connection 3 on USB Memory
USB memory with a capacity of at least 4MB is required for installation. Use of newly formatted USB
memory that does not contain any other data is recommended.

Using the procedure below to install Wireless Connection 3 on USB memory creates a file
named “autorun.inf” (which is a Wireless Connection 3 auto run file) in the USB memory root
directory. If the USB memory root directory already contains a file with the same name, the
existing file will be renamed by adding “.bak” or a three-digit number (.001, .002., etc.) to the end
of its file name.
