IRECTION
4-2-3-2 Complete Power Down
NOTE: This function is not available from Standby mode.
Follow this procedure to perform a complete system power-down
1.) Hold down the On/Off button for 3-5 seconds to evoke the display of the System Exit dialog box
(see
2.) Select Shutdown to do a complete power down of the unit.
The Back-End Processor will first turn OFF the scanner activity and print the message "Please wait
- Shutdown in progress" in the LCD display. Then system shut down commences.
The time required to power down the unit (including the Back-End Processor), may vary from
10 seconds up to approximately 1 minute. The last component that shuts down is the light in the
LCD display, indicating that you may continue with the next step.
3.) Disconnect the mains power from the wall outlet only after the fans have stopped. This will cut
power distribution within the unit.
If the system is still running when you disconnect the mains power, the internal power supply will
switch over to the battery power and supply the system with power until either the battery is drained
to 30% capacity (invoking shut down), or shutdown has been invoked by the user.
NOTE: To completely remove power from the system, release and remove the battery.
