RESETTING/INITIALIZING THE
SCANNER
If the scanner’s display locks up or does not work prop-
erly after you connect a power source, you might need to
reset or initialize it.
Important:
If you have problems with the scanner, first
try to reset it to retain all memory. If that does not work,
you can initialize the scanner; however, initializing clears
all information stored in the scanner’s memory.
