The Mitsubishi Monitor Test application requires MacOS 8.0 or later and MacOS Runtime for Java 2.0.
MacOS Runtime for Java is part of MacOS 8.1 and will be installed automatically with the system software. If Mitsubishi Monitor Test does not run correctly, make sure that Macintosh Runtime for Java (MRJ) 2.0 or later is installed.
To install Macintosh Runtime for Java, launch the "MRJ 2.0" disk image in the "Mitsubishi Monito Test folder". The image will be mounted on your desktop as a virtual volume named "Mac OS Runtime for Java". Launch the "Installer" to install MRJ 2.0.
