How to Scan

When the trigger is pressed, the scanner projects a red, horizontal illumi-

nating beam. This beam will remain on until the trigger is released, a bar

code is read, or until a time-out

period expires.

Linear Bar Codes —

To scan a linear bar code, center the illumination

beam over the bar code as shown in

Figure 6a. The scanner must “see”

across the width of all of the bars. Move the scanner further away from

the bar code to increase the scanning coverage area.

Stacked Bar Codes —

Stacked bar codes are read by holding in on the

trigger and moving the illumination beam in a smooth motion over the

bar code from top to bottom as shown in

Figure 6b. That motion should

be slow as well, since moving very fast will cause individual rows of the

stacked code to be overlooked, and will require extra sweeps to capture.

You will hear a series of ticks, followed by a final beep when the bar

code’s content has been completely decoded. You may need to sweep the

bar code several times in order to complete the read. Sweeps may be

made either from top-to-bottom or bottom-to-top.

1. Reference the Product Reference Guide (PRG) for more information about the aiming

beam time-out period.

NOTE

If the surface being scanned is highly reflective

(e.g., laminated), it may be necessary to tilt the item

or the scanner slightly (15° to 18°) to prevent

unwanted reflection.
