UPDATING THE MIDJAY
The Operating System of the MIDJAY resides in Flash memory and can be updated as follows.
After downloading the new operating system from the web site www.ketron.it, follow this procedure:
• Connect the MIDJAY to the Computer using the USB connection.
• Transfer the MIDJAYOS.BIN File from your computer’s Hard Disk to the MIDJAY, positioning the File in the
main directory and overwriting the homonymous MIDJAYOS.BIN File which is already there (Overwrite).
Warning: It is forbidden to disconnect the USB port or to turn OFF the MIDJAY during the data
transfer. This occurrence could cause a total destruction of the Files on Disk and a serious
malfunction of the Disk itself.
KETRON is not responsible for damages due to lack of compliance with these rules.
• Disconnect the USB cable (using the procedure for safe removal of hardware from the Computer) and wait
until the USB Connected message disappears from the display.
• Turn OFF and turn on again the MIDJAY. The instrument will display the message “New OS File has been
found. Install?”. This prompt explains that a new Operating System has been detected and asks if it should be
installed. Press Enter, while the “OK” function is active, in order to conrm the installation.
• The new program is automatically loaded while the 0-9 keys ash.
• When the system has been completely loaded, the MIDJAY is set for the initial operation Mode.
