Description of Device

Entering special characters, arith- metic characters and signs

Cursor keys

Most of the numeric keys have also been assigned special characters, arithmetic characters or the plus sign. The special characters are iden- tified 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 FN control key (see Figure 2-3) and, in addition, the appropriate numeric key.

If you release the FN 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 cursor keys on conventional PC keyboards:

Connecting	The keyboard layout for Windows 98 has been set to ºEnglish/USA
external keyboards	Internationalº. When using an external keyboard with the ºEnglish/
	USA Internationalº layout, the key codes of the internal and external
	keyboards are identical; for example, if you enter a ºyº on the external
	keyboard and a ºyº on the internal keyboard, you get a ºyº on the dis-
	play in either case.

2.1.3Integrated mouse

The integrated USB mouse with the two mouse buttons is a ºpiezo mouseº, i.e. the direction of the mouse pointer movement is determined by the pressure 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 ºSystem Setting/Mouseº.

If you wish, you can also connect an external mouse via the front USB (refer to Section 2.3).
