4. Hardware Features
4.1 Keypad
The DSV2+ comes equipped with a backlit, 5-button keypad, shown at
right. The upper four keys are function-keys, and are vertically aligned
along the left side of the LCD display, enabling application software to
position “virtual buttons” appropriately. These keys are initially
programmed as standard “F1” through “F4” keys and are mapped as
cursor (arrow) keys.
Below the four function keys is the power switch. The power switch
has a bi-color (red/green) backlight indicator, which identifies whether
the system is on, charging, or running low on battery power. To turn
the unit on, you must depress and hold the power switch until a single
beep is heard, then immediately release it for an additional two beeps.
Holding the button too long will cause an “error” type beep sound and
the system will not be powered up or down, as the case may be. This
procedure helps to guard against accidental activation or shutdown of
the system.
