Rockwell Automation 2755-G6-D Scanner with RS-232 Option - Manual (Page 23)

Using the Scanner
Chapter 3
3–7
When scanning a bar code symbol, listen for one
short, high tone. It means the bar code has been
decoded successfully.
A low-high-medium sequence of beeps on power up
means the scanner has been configured in a
continuous power mode for operation with serial
communication devices.
Hold at an Angle
Do not hold the scanner directly over the bar code. In
this position light can reflect back into the scanner
and prevent decoding. Angle the scanner slightly.
Scan the Entire Symbol
•
Move the scanner so the beam crosses every bar
and space on the symbol.
•
The larger the symbol the farther away you should
hold the scanner.
•
Hold the scanner closer for symbols with bars that
are close together.
•
If you have difficulty reading a label hold the
scanner beyond the recommended range in Table
3.B and then move the scanner closer.
