Symbol MS3204 Specifications 7 - 11
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 Methodon page 2-8
describes how to calculate the usable scan length. The
scan angle is provided in

Notes:
1. Contrast measured as Mean Reflective Difference (MRD) at 650 nm.
2. Near ranges on largely depend on the width of the bar code and the scan angle.
3. Working range specifications: Photographic quality symbols, pitch = 15°, skew = 0°, roll = 0°,
ambient light < 150 ft. candles, and temperature = 23 °C, Vcc = 5V.
4. Measured from the front of the scanner.
