Edition 07/02

Most of the numeric keys have also been assigned special characters,

arithmetic characters or the plus sign. The special characters are identified

in white, in the top left corner of the keys concerned.

To enter the plus sign, the special character or the arithmetic character you

require, press the F

control key (see Figure 2-3) and, in addition, the ap-

propriate numeric key.

If you release the F

key, you can return to entering the characters of the

basic numeric key assignment.

The cursor keys are used for navigation (e.g. for scrolling) or to move the

cursor. The following figure indicates the equivalents of the Panel PC cur-

sor keys on conventional PC keyboards:

equivalent to “PAGE ↑”

The keyboard layout for Windows 98 has been set to ”English/USA

International”. When using an external keyboard with the ”English/

USA International” layout, the key codes of the internal and external

keyboards are identical; for example, if you enter a ”y” on the external key-

board and a ”y” on the internal keyboard, you get a ”y” on the display in

either case.

2.1.3 Integrated mouse

The integrated USB mouse with the two mouse buttons is a ”piezo mouse”,

i.e. the direction of the mouse pointer movement is determined by the pres-

sure position on the center circular button and the speed of the mouse

pointer movement by the intensity of the pressure. The

parameters can be modified under ”System Setting/Mouse”.

If you wish, you can also connect an external mouse via the front USB (re-

fer to Section 2.3).
