Epson 386/25 - Manual (Page 54)

When num lock mode is on, you can use the numeric keys on
the keypad to enter numbers. The initial num lock option in the
Setup program determines whether num lock is on or off when
you turn on your computer.
To turn num lock mode off, just press Num Lock. The
Num Lock light (on the keyboard) goes out and num lock is
disabled until you turn the computer off or until you press
Num Lock again. The next time you turn on your computer,
num lock returns to the setting you selected in the Setup
program.
Note
If you are using the keyboard that came with your computer
(or another IBM AT compatible keyboard), the default for
the initial num lock setting is ON. If you are using a keyboard
that has 83 or 84 keys, the initial num lock default setting is
OFF.
The keyboard repeat rate option lets you change the speed at
which your keyboard repeats a character when you hold down a
key. The default setting
is Normal, but you can make the rate
faster or slower.
Follow these steps to check or change the keyboard and speaker
options:
1. At the main Setup menu, highlight Keyboard/ Sound.
The current settings appear:
Speaker Enabled
Initial num lock ON
KB repeat rate Normal
