Step 3 - X-PRESS Configuration

The Matrix 120 models are factory calibrated at three focus positions (45, 70
and 125 mm for WVGA models; 45, 80 and 125 mm for MP models). Using a 2.5
mm Hex key (Allen wrench), rotate the Focus Adjustment Screw at the back of
the reader to one of these three positions for your application.
Do not rotate the Focus Adjustment Screw beyond the focus scale limits otherwise
damage can occur to the focus mechanism.
CAUTION
Refer to the Reading Diagrams in
reading ranges at the different focus positions for Code 128 (1D) and Data
Matrix (2D) codes.
