Series 3800 Product Reference Guide
Scanning
Before scanning can occur, the terminal must be running an application that supports bar
code scanning. The terminal must also be programmed to scan the type of bar code you want,
such as Universal Product Code (UPC) or Code 3 of 9. For information on scanning
applications and on programming the scanner, refer to the Series 3000 ADK.
Entering Data Using the Laser Scanner
1. Pull the trigger on the terminal handle to power on the terminal and laser scanner.
2. Hold the terminal within the specified range of distance from and at a slight angle to
the bar code you wish to scan and pull the trigger.
3. Adjust the aim so that the thin, red laser beam covers the entire length of the bar
code. Do not hold the scanner directly over the bar code. The larger the bar code, the
farther away you should hold the scanner.
Optimal scanning distance varies with bar code density and scanner optics, but more
combinations work within 4 to 10 inches.
4. If the decode is successful, the screen displays the code and the green LED flashes.
The terminal may also beep.
Note: The procedure for your scanner may differ from the one given above.
Scanner use depends on the application.
Scanning Considerations
Usually, scanning is a simple matter of aim, scan, and decode, and a few quick trial efforts
master it simply and intuitively. However, two important considerations can optimize any
scanning technique — angle and range.
