Mounting angle and mounting distance

Set the angle and reading distance by referring to the read range characteristics
and angle characteristics described on P.122 to P.124.
The allowable reading distance and angle may vary depending on the narrow bar
width of the bar code, the bar code size, and the readability of the bar code. Set
these parameters after performing a test read of the required bar code using the
unit.

Note: Do not set the unit at an angle at which the laser beam is perpendicular to
the surface of the bar code. The beam will be fully reflected into the reader, making
correct reading impossible (

➮ See P.124).

The reading check test mode allows you to set the optimal reading position.

➮ To use the test mode, see P. 38.
