To switch the system ON: While holding the X3 unit, press the latch underneath the unit to release the leg, then pull the leg down and outwards until fully extended. From here, place the unit on the ground or floor in its intended operating position. Once the leg is open, press the power button. To switch the system OFF: Lift the X3 unit and push the leg back to its closed position until the latch clicks.  CAUTION: Keep fingers clear.  The unit will proceed to retract its feet and shut down the processor. Alternatively press the power button if the unit is not going to be packed away. NOTE: The shutdown time can be up to 30 seconds.
