Keyboard Protection Ribs
These ribs protect the keyboard and prevent keys from being pressed accidentally when the
terminal is placed facedown on a flat surface. For a complete overview of each keyboard, see
Using the Keyboards on page 4-1.
Touch Panel Display
The 3.5 inch 1/4 VGA (Video Graphic Array) display is a transflective color LCD (Liquid Crystal
Display) in TFT (Thin Film Transistor) color with a 240 x 320 resolution. The LCD is covered
by an industrial touch screen lens for maximum durability and backlit for maximum viewability;
see Backlight on page 6-8.
For touch panel input, use the stylus included with the terminal or your finger. The method you
choose depends on which one is most appropriate for your application. While there is a great
deal of variation in different applications, use of the supplied stylus provides greater touch
screen accuracy; see Using the Stylus on page 2-3.
Dolphin terminals ship with screen protectors already installed. Screen protectors help prevent
wear and damage to the touch panel; especially when used with applications that require high-
volume interfacing with the touch panel. Screen protectors are subject to wear and tear.
Therefore, inspect screen protectors regularly and replace them when worn or punctured.
Using sharp objects, such as paper clips, pencils, or ink pens and may cause damage
not covered by the warranty.
