Aiming
Do not hold the scanner directly over the bar code. Laser light reflecting directly back into
the scanner from the bar code is known as specular reflection. This specular reflection can
make decoding difficult.
You can tilt the scanner up to 45° forward or back and achieve a successful decode (Figure
2-9). Simple practice quickly shows what tolerances to work within.
