Using the Gryphon™ D432/D412Plus
The Gryphon™ D432/D412Plus hand-held reader aiming
system is designed for general reading and decoding of
1D and 2D symbols. Some variation in reading distance
will occur due to narrow bar width and other factors.
When reading codes positioned on reflective surfaces, it
may be necessary to tilt the reader with respect to the
barcode.
