Getting To Know Your Omnii 2 - 18
• EA11 2D imager: reads 1D and 2D barcodes including damaged and low contrast regular 1D barcodes.
Smallest barcode at 5 mil with a minimum read distance to 2.8 inches and a maximum read distance of 5.1
inches; largest barcode at 40 mil with a minimum read distance of 3.1 inches and a maximum distance of
32.4 inches.
• EA20X 2D imager: reads 1D and 2D barcodes including damaged and low contrast regular 1D barcodes.
Smallest barcode at 6 mil with a minimum read distance of 6.1 inches and a maximum read distance of 9.1
inches. Largest barcode at 40 mil with a minimum read distance of 5.1 inches and a maximum read dis-
tance of 49.2 inches.
• SE4600LR imager: captures digital images for transmission to a decoder to decode a barcode of any
format supported by the decoding software. Uses laser aiming, LED illumination, and CMOS sensors to
capture barcode images over an extended range and under a wide variety of lighting conditions.
Basic Scanner Operations
• Turn the hand-held on. Wait until the unit has booted up completely.
• Aim at the barcode 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.
Scanning Techniques
• Hold the scanner at an angle. Do not hold it perpendicular to the barcode.
• Do not hold the scanner directly over the barcode. In this position, light can reflect back into the scanner’s
exit window and prevent a successful decode.
• Scan the entire barcode. If you are using a 1D or PDF laser scanner, make certain that the scan beam
crosses every bar and space on the barcode, 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 barcode you want to scan.
• When using imaging scanners, do not move the scanner while decoding the barcode. Movement blurs
the image.
• Hold the scanner farther away for larger barcodes.
• Hold the scanner closer for barcodes with bars that are close together.
Scanner Status LED, Sounds, and Vibrations
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 barcode 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 the
Scan Indicator . (Refer to “Scan
Indicator” on page 4-90
.
When the scan is successful, the barcode data is displayed on the screen until the scan button (or pistol
trigger) is released, but only if the
Scan Result parameter is turned on. Refer to “Scan Result” on page 4-90 .
You can also enable sounds and vibrations to indicate good and bad scans by enabling Good Scan Beep and
Bad Scan Beep and Good and Bad Scan Vibrates. Refer to “Good Scan Beep and Bad Scan Beep” on
page 4-91 for details.
