Scanning 2 - 5
Aiming
Do not hold the scanner directly over the bar code. Laser light reflecting directly b ack into the scanner from the bar
code is known as specular reflection. This specular ref lection can make decoding difficult.
You can tilt the scanner up to 55° forward or back and achieve a successful decode (Figure 2-3). Simple practice
quickly shows what tolerances to work within.
