Step 6 — Position Symbol and Scanner
1. Set up a symbol at the scanning distance you will be using in your
application.
Note: If using an I 2/5 symbol, verify that the number of characters
in the symbol being scanned matches the symbol length enabled for
the I 2/5 symbol type (default is 10 and 6).
2. Avoid bright light or IR light from other sources, including other
readers.
3. Pitch the symbol or reader at a minimum of ±15° to avoid specular
reflection (the return of direct, non-diffused light).

tain as to your symbology type, enable all symbologies by selecting
