Cleaning the Disk Drive Read/Write Head Clean the read/write head regularly. This instrument employs a precision magnetic read/write head which, after an extended period of use, will pick up a layer of magnetic particles from the disks used that will eventually cause read and write errors. To maintain the disk drive in optimum working order Yamaha recommends that you use a commercially-available dry-type head cleaning disk to clean the head about once a month. Ask your Yamaha dealer about the availability of proper head-cleaning disks. • Never insert anything but floppy disks into the disk drive. Other objects may cause damage to the disk drive or floppy disks. Using Floppy Disks Be sure to follow these precautions when using floppy disks: • Do not place heavy objects on a disk or bend or apply pressure to the disk in any way. Always keep floppy disks in their protective cases when they are not in use. • Do not expose the disk to direct sunlight, extremely high or low temperatures, or excessive humidity, dust or liquids. • Do not open the sliding shutter and touch the exposed surface of the floppy disk inside. • Do not expose the disk to magnetic fields, such as those produced by televisions, speakers, motors, etc., since magnetic fields can partially or completely erase data on the disk, rendering it unreadable. • Never use a floppy disk with a deformed shutter or housing. • Do not attach anything other than the provided labels to a floppy disk. Also make sure that labels are attached in the proper location. Protecting Your Data (Write-protect Tab) To prevent accidental erasure of important data, slide the disk's write-protect tab to the "protect" position (tab open). If you attempt to modify the disk when the write-protect tab is set to "on" position, a "Disk write protected!" or "Disk error!" message appears in the display, indicating that the operation is not possible. (Select "OK" at the prompt, and change the tab setting, if desired.) Rear side Shutter Protect Off (tab closed: unlocked) Write-protect tab Protect On (tab open: locked) Data Backup For maximum data security Yamaha recommends that you keep two copies of important data on separate floppy disks. This gives you a backup if one disk is lost or damaged. To make a backup disk use the Disk Copy function on page 111. Disk Compatibility Floppy disks containing data recorded on the AR-100 Electone can also be used on the AR-80, with virtually complete compatibility. However, since there are some minor differences between the two models (especially in Voices, Extra Voices, Registrations, and Registration Menus), data compatibility is not absolute. If you are using AR-100 disks with the AR-80, the following minor incompatiblities may occur: • In AR-100 song data, if a selected Voice is not available on the AR-80, the first Voice in the same category will be selected. • For AR-100 song data using Extra Voices and Flute Voices, only those Extra Voices and Flute footages that are common between the two models will sound. • AR-100 song data using Registrations 13 16 will play properly. However, when these Registrations are selected, none of the Registration buttons will be lit. • AR-100 Registration Shift data using Registrations 13 - 16 will function properly. However, these Registrations appear "ghosted" in the Registration Shift display. 84
