Keyboard
The Dolphin 9500/9550 series features three keyboard options: 35-key numeric/alpha keyboard, 43-key numeric/alpha
keyboard, and 56-key full alpha/numeric keyboard. Each keyboard is backlit for easy viewing in various lighting
conditions and contains centrally located keys for both right- and left-hand operation. The silver background of both the
keys and the overlay enhances the readability of each.
The overlay of all three keyboards are color-coded to indicate the functions performed or characters typed when the
color-coded key is pressed immediately after the Red or Blue Modifier key at the bottom of the keyboard.
