Copy the downloaded firmware file to the root folder (highest folder in the hierarchy) of the USB storage device.
The USB storage device must be formatted in FAT format.
Do not copy any other files to the USB storage device.
Do not change the firmware's file name. If the file name is changed, the firmware update will not start.
Check that the firmware file you copied is the correct file for your projector model. If the firmware file is not correct, the firmware update will not start.
Connect the USB storage device to the projector's USB-A port.
