Notes:

1. CONTRAST measured as Mean Reflective Difference (MRD) at 650 nm.

2. Near ranges on lower densities are largely dependent upon the width of the bar code and the scan

angle.

3. Working range specifications: Photographic quality symbols, pitch = 10°, skew = 0°, roll = 0°, ambient

light < 150 ft. candles, and temperature = 23 °C
