What to Do After Receiving the V550-A20
Tilt is the way the bar code rotates around the tilt axis. Similarly,
pitch and skew occur when the bar code is rotating around those axes.

The Exit Window is where the laser beam exits the scanner. Near
Distance
, also called
Optical Throw
, is the closest the V550-A20 can
be to the bar code and still read the bar code passing through its scan
line. The
Far Distance is the farthest distance at which the V550-A20
can read a bar code. The Depth of Field is the range over which the
V550-A20 can read bar codes. To calculate your Depth of Field,
subtract the Near Distance from the Far Distance. The V550-A20's
Optimum Distance is the Center of the Depth of Field. The Scan
Window is the usable amount of the laser beam at any given depth of
field.
