(PowerLite
975W/2055/2065/2155W/2165W/2245U/2250U/2255U/2265U). Do not
install any other type of wireless LAN module.
Note: The
wireless LAN module is optional for the PowerLite

Caution:
Never remove the module while its
indicator light is blue or flashing, or
while you are projecting wirelessly. You may damage the module or
lose data.
