codes, useful when decoding low-profile 1D and 2D bar codes where over-scanning is not
desired. Note that the height and expansion rate are directly, but not linearly, proportional to
their respective parameter values.

Aiming Modes

There are two aiming modes: aiming with a dot pattern, or with a slab raster pattern. Note
that aiming modes do not work with the Always Raster scanning option.

Aiming Dot Option

A trigger pull creates the single dot aiming pattern, which lasts for a fixed interval. This dot
can easily be seen in outdoor or high ambient light environments. A slab raster pattern or an
open raster pattern appears next, depending on the programmed scanning option. There are
two programmable timeout periods for this option — normal and extended.

Slab Raster Option

A trigger pull creates the slab raster pattern. If the target is a 1-D bar code, the pattern never
gets beyond a slab raster. If the target bar code is PDF417, the pattern opens up to an
optimized raster pattern as soon as the scanner is properly aligned over the bar code.

Scanning 1D Bar Codes

To scan a 1D bar code:
1. Make sure all connections are secure, and the symbol you want to scan is within the
scanning range (refer to
2. Aim the scanner at the symbol and press the trigger. The scanning beam remains on
for approximately 3.0 seconds (default) or until a successful decode.
The scanner has read the symbol when:
You hear a short, high tone beep (if the beeper is enabled).
!
The green LED on the scanner lights.
!
The green LED stays lit for one second or until the next trigger pull.
