s"Preparing a Scenario" p.48.
You can also play audio (.wav) files set as BGM at 
the time of scenario creation.
You can also project scenarios created using the 
EMP SlideMaker that is supplied with the EMP-

• JPEG files with the extension ".jpeg" and MPEG files 
with the extension ".mpeg" cannot be projected.
• When projecting JPEG files, the image will not be 
projected clearly if compression is set too high.
• If you use a USB storage device with a slow access speed 
when playing back movies and scenarios with BGM (when 
transmitting at higher bit rates), the movie files may not 
play back correctly or the sound may skip or not be output.
When using a USB hard disk, we recommend using an AC 
adaptor power supply.
• Use the following formats when formatting the media to be 
used.
USB memory  FAT16/32
USB hard disk  FAT16/32
