You might encounter some issues when you
scan bar codes. This chapter provides

Scanner issues
My scanner doesn’t emit the aiming pattern.

Did you charge your scanner?

Did you turn off the aiming pattern?
■
Your battery wears out. Replace the
battery and make sure the new battery is
charged.

Your scanner is waiting your computer to
acknowledge data and doesn’t receive any
response. Unplug your cradle’s cable (USB

devices and test if they work properly. If
not, replace them and charge your
scanner again.
