loaded from a floppy disk. This section describes the protection and handling
of such floppy disks.

Backing up the Data and Program
A floppy disk is a compact and light weighted data storage medium convenient for storage and
transport, but data may be erased or may not be loaded by improper handling.
Make sure to back-up the program and data on a disk to protect against the loss of data. To back-
up the program and data, make another copy disk of the same contents.

Write Protection
The stored data may be mechanically protected from accidental erasure or rewriting.
• Write protection may be set or disabled by sliding the write protect tab located at the lower part of
the floppy disk with a ball pen tip, etc.
Slide the tab with a ball point
pen tip or something similar.
