Honeywell 4820 Photo Scanner User Manual


 
1 - 10
The aiming beam is smaller when the image scanner is closer to the code and
larger when it is farther from the code. Symbologies with smaller bars or ele-
ments (mil size) should be read closer to the unit. Symbologies with larger bars
or elements (mil size) should be read farther from the unit. To read single or
multiple symbols (on a page or on an object), hold the image scanner at an
appropriate distance from the target, pull the trigger, and center the aiming
beam on the symbol. If the code being scanned is highly reflective (e.g., lami-
nated), it may be necessary to tilt the code up 15° to 18° to prevent unwanted
reflection.
