System ucom and DSP Version Upgrade
System µcom and DSP can be upgraded in the following manner.
Version Upgrade Method
(1) Record the version upgrade software on a CD-R or CD-RW disc, only as one file with the format ISO9660 Mode-1.
The file name of the supplied version upgrade software should be used as is and this disc needs to finalize.
(2) After loading the disc made in above step 1, turn off the power. Then, turn on the power while pressing the MODE button and PITCH BEND button. The version upgrade starts with reading data of the disc.
(3) When you start version upgrade operation, messages "Version_Up" and "System&DSP" are displayed on the character display. Recovery positions are turned on one by one from the left end according as the upgrade operation proceeds. When this operation is completed, all recovery positions are turned on. In case of some error or the power is turned off during the version upgrade, it may be impossible to operate at all thereafter.
Changing of IC502 on GU-3482 is necessary in this case, and software writing to IC502 should be done beforehand.
(4) When the upgrade is completed, the disk is ejected and operation returns to the normal mode.
(5) File name of the upgrade software indicates version numbers.
