ATTENTION: Many electronic components in the
scanner are static sensitive. Anyone servicing the
scanner should be well grounded through an ESD strap
and ground cord. For additional protection from static
discharge, the scanner should be attached to the
decoder.

Smudges from fingerprints will deteriorate read
performance. The internal mirrors cannot be serviced
in the field.
