Intermec 751G 用户手册

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 Intermec representative for more information.

The minimum standard reading distances for 751Gs built with integrated 
scan engines are shown below. When correctly mounted, an exit window 
reduces reading distances by about 4%.
