The power switch for the CR-L1 is located on the back of the scanner on the left side.
Solution
To turn the scanner ON, slide the power switch to the right.
When you turn ON the power, the power LED flashes slowly, and then turns solid.
If the scanner does not work, there could be a problem with the scanner. Turn the scanner OFF.
If you hear strange sounds, detect smoke or abnormal heat, sense a vibration or small odd odors around the scanner, turn OFF the power immediately and disconnect the power cord from the power outlet.
