1. Ensure that the MC21XX is loaded with a scanning application. See DataWedge on page 3-5 for more
information.
2. If the MC21XX is equipped with a rotating head, adjust the head prior to scanning.
3. Aim the scan window at the bar code.

illuminate red to indicate that the beam is on. The LED Indicator turns green and a beep sounds to indicate
a successful decode.
