Touch Screen Display
The 3.8" liquid crystal display (LCD) is covered with an industrial, protective touch screen lens. The video graphic
array (VGA) resolution is 1/4 (240 X 320 pixel). The color LCD is 16 bits/pixel and uses active display or thin film
transistor (TFT) technology. By default, the display backlight lights when the screen is touched. For more details,

is appropriate for your application. While there is a great deal of variation in different applications, for buttons
or icons that are close together, you generally achieve greater accuracy with the stylus. Use of other objects,
such as paper clips, pencils, or ink pens can damage the input panel and will void the warranty.
Hand Held Products recommends using screen protectors to protect the touch screen; especially when used with
applications that require high-volume interfacing with the touch screen. Screen protectors help prevent damage to
the touch screen display and are easily installed. Screen protectors can be purchased at any major computer retail
store or directly from Hand Held Products; contact Hand Held Products directly for part numbers and pricing.
SCAN Key
The SCAN key is centrally located for easy access with the right or left hand. When pressed, the SCAN key
activates the scanner/imager. The SCAN key also functions as an on or system wakeup control for the terminal.
Navigation Keys
The centrally-located navigation keys enable you to move and position the cursor through software programs. The
up and down arrows are programmed to perform specific functions when pressed in combination with the Blue and
Red modifier keys.
Recessed Keyboard
The Dolphin 7900 Series features two keyboard options: 25-key numeric and 36-key alpha keyboard. Both
keyboards are recessed under the overlay for maximum durability and backlit for easy viewing in various lighting
conditions. For a complete overview of each keyboard, see
