Laser Class
Class1 Laser Product (IEC60825-1)
Class Laser Product (FDA (CDRH) Part1040.10)
CAUTION
• Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
• Do not look directly at laser light or reflected laser light from a mirrored
surface. Otherwise, eye injury may result. Laser light will not cause damage if
it strikes exposed skin, but laser light should not deliberately be aimed
towards a human body.
• Do not disassemble the BL-N90 Series. The BL-N90 Series does not
automatically stop emitting the laser when the reader is disassembled.
Therefore, if someone disassembles the reader, he/she may be exposed to
the laser beam and may suffer eye injury.
• Be sure to stop the laser emission before cleaning the portion of the laser
scanner where laser light is generated and received (transmitter/receiver).
Otherwise, exposure to the laser may cause eye injury.
• Be careful of the path of the laser beam.
Be especially careful of reflected laser light from a mirrored surface.
Do not use the BL-N90 Series where the path of the laser beam is at the
same height as that of the human eye.
