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 into CD1, turn off the power. Then, turn on the power while pressing theOPEN/CLOSE button of CD1. The version upgrade starts with reading data of the disc. No disc should be loaded intoCD2.3. TRAY LED of both CD1 and CD2 will turn on when the version upgrade starts, and they will turn off when the versionupgrade ends.? TRAY LED of both CD1 and CD2 will blink if the version upgrade ends abnormally due to error etc.? In case of some error or the power is turned off during the version upgrade, it may be impossible to operate at allthereafter. Changing of IC502 on GU-3412 is necessary in this case, and software writing to IC502 should be donebeforehand.4. Turn off the power after finishing the version upgrade, and turn on again to take out the disc.5. File name of the upgrade software indicates version numbers.6. ROM Drive (FG-9000) com Version UpgradeDrive (FG-9000) com can be upgraded in the following manner.Version Upgrade Method1. 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 turning on the power, load the disc made in above step 1 into the mecha. you want to upgrade the version.3. “Drive” and “Version UP?” are indicated in the character display. Press the OPEN/CLOSE button and remove the discwhen not upgrade the version.4. Press the PLAY/PAUSE to start the version upgrade. “Now Loading” is indicated.5. When the version upgrade is finished, “Complete” is indicated and the tray opens.6. Turn off the power once and turn on again after take out the disc.?The version upgrade ends in 2030 seconds normally. If the power turned off underway or the version upgrade endsabnormally, the drive may become malfunction. In such a case, version upgrade with PC will be needed.7.
