codes (5 - 55mil) at medium distances (up to 1m).
•
1D Imager: reads regular 1D and PDF417 bar codes at short to medium distances.

Basic Scanner Operations
•
Turn the hand-held on. Wait until the unit has booted up completely.
•
Aim at the bar code and press the scan key or the trigger. A scan beam and a warning
indicator appear until a successful decode is achieved or six seconds have elapsed.
6.9.2
Scanning Techniques
•
Hold the scanner at an angle. Do not hold it perpendicular to the bar code.
•
Do not hold the scanner directly over the bar code. In this position, light can reflect back
into the scanner’s exit window and prevent a successful decode.
•
Scan the entire bar code. If you are using a 1D or PDF laser scanner, make certain that
the scan beam crosses every bar and space on the bar code, including the margins on
either end of the symbol.
•
If you are using a 2D imaging scanner, make certain the red, oval shaped framing mark
is centered within the bar code you want to scan.
•
When using imaging scanners, do not move the scanner while decoding the bar code.
Movement blurs the image.
•
Hold the scanner farther away for larger bar codes.
•
Hold the scanner closer for bar codes with bars that are close together.

Scanner Status LED
The scanner LED (the far right LED) indicates whether or not your scan is successful. The
LED behaves as follows:
•
Scan In Progress: scan LED displays solid red colour.
•
Successful Scan: scan LED displays solid green colour and turns off when the scan
is ended.
•
Unsuccessful scan: scan LED flashes red.
A bar code icon appears on the screen during a scan. While the scanner beam is active, the
onscreen message states: SCANNING. If you want to turn off the onscreen message, disable
“Scan Indication” in the
Options
tab in the
Control Panel>Scanner Settings
menu.
