Check synchronization of reading pulse with object to read:
Is the scan line correctly positioned?
Place barcode in the center of scan line and run Test mode
(selectable by Genius™ as an Operating Mode). If you still have
trouble, check the following:
 Is the reading distance within that allowed (see reading
diagrams)?
 Is the scanner correctly focused?
 Is the Tilt angle too large?
 Is the Skew angle less than 15° (direct reflection)?
 Choose the Code Definition branch and enable different
Code Symbologies (except Pharmacode). Length = Min
and Max (variable).
 Is the Bar Code quality sufficient?
If you had no success, try to perform the test using the
BARCODE TEST CHART included with the product.

 If using CBX, be sure the RS485 termination switch is
positioned to OFF.
