Please observe the following when handling floppy disks: - Never touch the magnetic medium inside the disk. - Do not subject floppy disks to temperature extremes (eg., direct sunlight in an enclosed vehicle). Recommended temperature range: 10 to 50°C. - Do not expose floppy disks to strong magnetic fields, such as those generated by loudspeakers. • Floppy disks contain a 'write protect' tab which can protect the disk from accidental erasure. It is recommended that the tab be kept in the 'PROTECT' position and moved to the 'WRITE' position only when you wish to write new data onto the disk. • All important data should be copied onto backup disk(s). This provides a complete duplicate of the data should the original disk(s) be lost or damaged. • The identification label should be firmly fixed to the disk. Should the label come loose while the disk is in the drive, it may be difficult to remove the disk. • Put the disk back into its case for storage. 3 Part Names Front Panel Rear Panel See page 4 of the MT-1 20 Owner's Manual for these descriptions.
