The header conforms to IEEE 1394a specification. The IEEE 1394a header can provide one IEEE
1394a port via an optional IEEE 1394a bracket. For purchasing the optional IEEE 1394a bracket,
please contact the local dealer.
• Do not plug the USB bracket cable into the IEEE 1394a header.
• Prior to installing the IEEE 1394a bracket, be sure to turn off your computer and unplug
the power cord from the power outlet to prevent damage to the IEEE 1394a bracket.
