Note: A scanning application and scanner driver must be loaded on the
terminal to perform scanning.

Using the Scanner

To use the integrated laser scanner:
1. Verify that the system is on (the display is active).
2. Ensure that a scanning-capable application is loaded and running, and that the
application is in a state to allow scanning.
3. Aim the scan window at the bar code.
4. Adjust the aim so that the thin, red laser beam covers the entire length of the bar
code.
Wrong
Optimal scanning distance varies with bar code density and scanner optics, but most
combinations work within 4 to 10 inches. Generally:
" Hold the scanner farther away for larger symbols.
" Move the scanner closer for symbols with bars that are close together.
5. Press the scan button.
6. If the decode is successful, the LED turns from yellow to green. The terminal may
also beep.
