Note  2: Some input sources may not be displayed properly because they are not compatible with the projector.Note  1: MAC adapter is necessary to set the resolution mode.
Projector is compatible with 13 inch mode and 16 inch mode.
Set all dip switches OFF except those indicated in the chart.
For example:
MAC 13 mode = switch 1, 5 and 6 are ON
MAC 16 mode = switch 2, 5 and 6 are ON
(Example of 16 inch mode)

(2) Turn ON the projector.
(3) Turn ON the computer.
(4) Select the correct mouse driver for the application.  See computers User Manual for this procedure.
4 Note
In some Notebook computers which have internal pointing device, mouse emulation will not work unless the
internal pointing device is disabled.  In this case, disable the internal pointing device in BIOS setting.  Check
the computers manual for procedure to follow to disable internal pointing device in BIOS setting.
Caution
Turn off the power to both the projector and computer before connecting. Connect the computer to the
control terminal of the projector using the appropriate cable.
