Getting Started

Per FDA and IEC standards, the engine described in this guide is not given a laser
classification. However, the following precautions should be observed:

Caution

This laser component emits CDRH Class II/IEC Class I laser light. Do not
stare into beam.

Overview

The SE4400 provides digital images which can be transmitted to a decoder to decode a bar
code of any format supported by the decoding software. The SE4400 uses laser aiming and
LED illumination, and can switch between two focus positions for extended working range
or for more precise focusing in high-density bar code decoding or digital picture taking.
