Setup and Operation


2-5

2.2.1 Monitor

Touch screen The surface of the monitor is covered by a touch-sensitive plas-tic sheet that senses the pressure of a finger or of the supplied touch-pen and transfers it to the system. This special surface is referred to as a touch screen. It replaces the conventional function of a mouse or keyboard.

Important

The touch screen reacts to any tactile contact. When you are us-ing the operating unit, make sure it is protected against inadvert-ent contact by devices or persons.

Caution

Only use your finger or the supplied touch-pen to operate the touch screen. If other objects are used, this can damage the sur-face and under certain circumstances make it necessary to re-pair the GT1. The repair will be charged.

Select To select display elements such as texts, fields or buttons, you have to touch these at the appropriate point on the touch-screen surface. These are then highlighted by a change in color:

• Texts are highlighted in a bright color and with a dark selection bar

• Buttons assume a dark-gray color and appear in a sunken perspective (relief).

As long as you are still touching the touch-screen surface, you can change the selection. If you stop touching the screen, the selected element is activated and the corresponding function is started. In the following, this operation is referred to as pressing.

Touch-pen The touch-pen is an ergonomic operating aid for the touch screen and it makes it easier to operate the displays: you can use its tip, for example, to make targeted selections of screen ele-ments that are too small to operate using your finger.

Setup and Operation

Fig. 2-3 Touch-pen

Virtual keyboard If the system asks you to enter data, a virtual keyboard appears in the screen display. It is operated in a similar way to that famil-iar to you from a conventional mechanical keyboard.

Note

The supplied optical keyboard is intended for service purposes only, not for the operation of the system.

The virtual keyboard can consist of a letter block (alpha-numeric keypad) and/or a numeric keypad.

Alpha-numeric keypad

If an alpha-numeric keypad appears on the touch screen, you can enter lower and upper case letters as well as blanks. You can read your input in the corresponding area on the touch screen.

Fig. 2-4 Alpha-numeric keypad

Note

If upper case letters are entered, they are reset to lower case as soon as they are keyed in!

Setup and Operation


2-7

Important

Please note that the arrangement of the alpha-numeric keypad corresponds to that of a US computer keyboard: some keys might therefore be located in different positions to those on a standard keyboard commercially available in your country. Spe-cial national characters such as accents, umlauts, etc. cannot be entered using the virtual keyboard.

Special keys The alpha-numeric keypad contains the following special keys:

• Upper case: these are two keys that are marked with an ar-row pointing upwards. If you press an upper case key, the let-tering of the keys switches from lower to upper case letters and vice versa.

• Backspace: this key is marked with an arrow pointing to the left. It deletes the last entered character.

• Return/Enter: this key is marked with an arrow pointing downwards to the left. It completes an entry or switches to the next line.

Numeric keypad If a numeric keypad appears on the touch screen, you can enter numerical values and possibly mathematical functions. You can read your input in the corresponding area on the touch screen.

Fig. 2-5 Numeric keypad (example)

Note

As required, it is possible that only a selection of the keys shown in the above example appears.

Special keys The numeric keypad might also contain special keys for basic arithmetical calculations (+ - * /) and a decimal separator.

Setup and Operation


2-8

Important

The only decimal separator you can use is a decimal point (period). Entering a comma leads to an error message.
