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 includin

g 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 successf

ul 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 pos

ition, 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

cro

sses 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

e 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. Wh

ile 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 Go

od 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.
