90 741 and 751 Mobile Computer (Windows Mobile 5.0) User’s Manual
If you are using the linear imager, the standard range laser, or the long range
laser, the computers support these bar code symbologies:
Scanner Reading Distances
Typical reading distances are done in an office environment using office
lights (4 lux). Minimum distances are measured in the dark (0 lux). Both
reading distances are provided in respective scan engine integration guides.
Contact your local Intermec representative for more information.
Below are minimum standard reading distances for the 741 and 751 built
with integrated scan engines. When correctly mounted, and exit window
reduces reading distances by about 4% for all scan engines, with the
exception of the EL10 with its reading distances reduced by about 25%.
