Power Modes
The VX3X has several distinct power modes.
• On Mode – When the VX3X is attached to either vehicle 12-80 VDC or an external
power supply and the power button is pressed, the VX3X is in the On mode. In this
mode, the keypad, touchscreen and any attached peripherals such as a scanner
function normally. The display remains on until the backlight timer (if enabled)
expires.
• User Idle Mode – If the Display Backlight Timer is enabled (see the Display section
in the Windows CE Control panel), the VX3X enters User Idle Mode when the
display backlight timer expires without any Primary Event (see below) to reset the
timer. The VX3X exits User Idle Mode with any Primary Event. The keypress or
screen touch that exits User Idle Mode is sent to the operating system. The VX3X
then transitions to On Mode.
