Power Modes 

VX7 Reference Guide 

E-EQ-VX7RG-H 

The VX7 has several distinct power modes. 

•  On Mode – When the VX7 is attached to either vehicle 12-80 VDC or an external 

power supply and the power button is pressed, the VX7 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 VX7 enters User Idle Mode when the display 
backlight timer expires without any Primary Event (see below) to reset the timer.  
The VX7 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 VX7 then 
transitions to On Mode.

•  System Idle Mode – The VX7 does not support System Idle mode. 

•  Suspend Mode – TheVX7 does not support Suspend mode.  However, if the 

Suspend timer is enabled, the VX7 transitions to Off mode when the Suspend timer 
expires. 

•  Off Mode – The VX7 turns off if the user presses the power button when the VX7 is 

On.  The VX7 is also off when it is not connected to a power source.  However, an 
internal Real Time Clock (RTC) powered by an internal battery maintains the date 
and time while the VX7 is off.
