If you are using bar code labels that are encoded in a different 

symbology, you need to enable the symbology on the computer. Use 

Intermec Settings to enable and disable symbologies. For help, see 

“Configuring the CN3 Parameters” on page 45.

Improving Imager Performance

If you experience problems reading bar codes, try some of these tips to 

improve imager performance.

•

Keep your hand as steady as possible while scanning a label.

•

Position the imager as close to the bar code as possible while still 

being able to capture the entire bar code.

•

Enable only the bar code symbologies that you need to use every 

day.

You can also choose a predefined mode that optimizes imager settings 

for different needs or environments.
