Interacting With the Touchscreen
The DMTouch display has no physical buttons or switches, all user interactions are carried out by pressing areas on the touchscreen
similar to a mobile phone or tablet PC. The touchscreen should be operated using your finger and care should be taken not to apply
excessive force as it could lead to damage. The DMTouch utilises a capacitive display technology and therefore objects such as pen nibs
or screwdriver tips will not operate the display. Either a finger or a dedicated tool, such as a capacitive stylus pen, should be used when
interacting with the DMTouch to provide the correct operation.
Each press of the display is accompanied by a click from the sounder. On some pages where lines of text are shown, such as the
parameter list, the user can scroll down the page by running their finger from the bottom to the top of the list in the same manner as with
a touchscreen enabled mobile telephone. During this motion the user’s finger should remain in contact with the touch screen.
Navigation Buttons
When entering information or setting parameters on the DMTouch, a keyboard will be displayed. Depending on the information that the
DMTouch is expecting, it will show one of two layouts. One is numerical and the other is alphabetic. The user can change between the
two by using the ‘ABC’ button on the numerical keyboard and the ‘123’ button on the alphabetic keyboard. Both these buttons can be
found in the bottom left of the keyboard.
See below for pictures of keyboard layouts
