Controlling
It is possible to attach a standard computer mouse or keyboard to the TDC-5000 PC through a USB port (or
a RS-232 in case of mouse). The mouse can be used to control the mouse cursor when using the operating
system. You can use the keyboard when entering text and controlling some elements of the operating system
and applications using keyboard shortcuts. The settings for the mouse and keyboard can be changed in the
system settings for the operating system.
An alternative method of control is by using the touch panel, which can be used to perform many operations
without using keyboard and mouse. The information you need to use the touch panel correctly is presented
in the following section.
Note: The way of controlling with the keyboard, mouse and touch panel may be different according to
the type of operating system used and its settings.
Controlling with the touch panel
The TDC-5000 PC is equipped with a resistive touch panel which allows you to control the mouse cursor or
enter text using the virtual keyboard on the display. The touch panel can be controlled by the touch of a finger
or using a special touch pen (stylus). If you use a keyboard or mouse and at the same time the touch panel
to control the computer, the individual methods of controlling will impact each other. Before using the touch
panel for controlling it is necessary to calibrate the touch panel; the procedure is described in the section
“Calibrating the touch panel“.
Notice: Control the touch panel by gentle pressure of the finger or stylus. Do not use excess pressure
or objects with hard and sharp edges for controlling; otherwise you may cause damage to the
touch panel or the display.

Controlling the mouse cursor with the touch panel
Using the touch panel you can control the mouse functions as follows:
Tapping on the screen is the equivalent of left-clicking the mouse – the cursor is shifted to the place of the
touch and the object beneath the cursor is selected.
Double-tapping – is the equivalent of double-clicking the left mouse button.
