Basic Operation and Navigation Turning On/Off, Sleep Mode and Emergency Shutdown
3.1.3 Sleep Mode
The Windows operating system uses Sleep Mode to conserve power by stopping all processes
and turning off the display screen, while keeping the diagnostic tool on and your open applications
active. When you are ready to resume work, the diagnostic tool can be started up again quickly,
just by pressing the Power button.
Sleep Mode settings can be found in Windows Control Panel > Power Options. For additional
information, refer to Windows 7 user documentation.
It is recommended that you terminate any current vehicle communication and save any open
working files or data before entering Sleep Mode, to avoid any ECM problems on some vehicles
or data loss from any unforeseen circumstances (e.g. power loss).
If Sleep Mode is accidentally activated during active vehicle communication, vehicle
communication will stop, and vehicle selection will be reset to “no active vehicle”.
z To enter Sleep Mode:
• Press and release the Power button.
The display screen will turn off and the LED backlit power button will light up red, blinking on
and off at two second intervals.
z To exit Sleep Mode (wake up):
1. Press and release the Power button.
The display screen will turn on and resume the last open application. Depending on settings,
you may need to select your user ID icon to open the last application.
3.1.4 Emergency Shutdown
Using the emergency shutdown procedure while communicating with the vehicle ECM may lead
to ECM problems on some vehicles.
During normal operation turn the Diagnostic Tool off using the Turning Off procedure above. The
emergency shutdown procedure should only be used as the last option, if the Diagnostic Tool does
not respond to navigation or control buttons or exhibits erratic operation.
To perform an emergency shutdown:
1. Press and release the Power button.
The display screen will turn off and the LED backlit power button will turn red and begin blinking.
2. Press and hold the Power button again, until the LED in the power button stops blinking.
