sequences is given later in this chapter.
3. Use the [SHIFT] key in conjunction with the 10 numeric keys and the [ENTER] key to access
nine common system menus, a help display function and a [CANCEL] key.
Assignment of functions to the keypad keys
The keypad contains 20 keys. Each of these keys has at least one function associated with it,
some keys have more functions. The following sections give descriptions and uses of each of the
keys on the keypad, as well as the diagnostic LEDs and the built-in display.
Improper Keypad Operation
Although the drive comes standard with a keypad interface, and the menu system is secured
with multiple, programmable password levels, for security or other reasons, the drive is capable
of running without the keypad.
