If a strong reflected light enters the receiver of the BL-600 Series, the reading may
fail or be unreliable.
If reflected light enters the receiver of another unit, the reading may be unreliable,
because of mutual interference.
If two or more bar code labels enter the laser beam at the same time, the BL-600
cannot be set to read a specific bar code.
➮ See page 67 to change the scanning width.
* When “Multi-label read mode 3” is specified, the BL-600 Series can simulta-
neously read up to 4 bar codes in the field of the laser beam.
