MS-2204VHD 2D Decode Distances
Note: Not optimized for omnidirectional mode.
Usable Scan Length
The decode zone is a function of various symbol characteristics including density, print
contrast, wide-to-narrow ratio, and edge acuity. Consider width of decode zone at any given
distance when designing a system.
Calculating The Usable Scan Length Method on page 2-14 describes how to calculate the
usable scan length. The scan angle is provided in the Usable Scan Length Diagram on
page 2-15.

Notes:
1. CONTRAST measured as Mean Reflective Difference (MRD) at 650 nm.
2. Near ranges on lower densities largely depend on 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.
