resetting/initializing your scanner
If the scanner’s display locks up or does not work properly after you connect a power source,
you might need to reset or initialize it. If you have problems with the scanner, first try
resetting it, which will retain items stored in memory. If that does not work, initialize the
scanner. You may be able to save the information in your scanner’s memory to your
computer, or another scanner before initializing it. See “Cloning the Programmed Data”.
resetting your scanner
1. Turn off your scanner, and then turn it on again.
2. Insert a pointed object into the reset hole on the back of the scanner. Then, gently press
and release the reset button. Pressing reset does not clear the scanner’s memory.
initializing your scanner
Initializing your scanner clears all information stored in your scanner’s memory. Initialize
your scanner only when you are sure it is not working properly.
1. Turn off the scanner, then turn it on again. WELCOME appears.
