LASER BEAM SAFETY
“Low power” lasers are by definition incapable of causing eye injury within the duration of the blink, or aversion response (0.25 s), and
must be visible (400 nm to 700 nm). Therefore, an ocular hazard can only exist if an individual overcomes his/her natural aversion to
bright light and stares directly into the laser beam. The product requirements for these lasers are two: to have a CAUTION label and to
have an indicator light to indicate laser emission.
The two operational safety rules are:
•
Do not permit a person to stare at the laser from within the beam.
•
Do not point the laser at a person’s eye at close range.
Follow the instructions on this datasheet for the adjustment and mounting of the V550-A20.
Make sure that the laser beam will not be directly or indirectly reflected into human eyes. The safety distance is approximately 1 m for the
V550-A20. If there is a possibility of laser beam reflection by any objects around the emitter at the time of adjustment, apply paint with a
low light reflection ratio to the objects.
The sensor incorporates laser emission warning light and a “scanning safeguard” feature which shuts off the laser power if the mirror
wheel fails to rotate. This ensures that a stationary laser beam cannot emanate from the scan head.

LASER CONTROL REGULATIONS
The V550-A20 Bar Code Reader meets the standards required by
the U.S. Food and Drug Administration (FDA). This reader also has
been reported to the Center for Devices and Radiological Health
(CDRH). Any service performed on this device should be done so
as to not violate compliance with the
Code of Federal Regulations,
Title 21, Part 1040, Section 10 (21 CFR 1040.10).
Labels (FDA Regulations)
Laser radiation warning and information labels are located on the
top side of the bar code reader.
■
INSTALLATION
Install the bar code reader in a location where the laser beam will not enter the operator’s eyes directly or from reflection by a mirror
surface. Also, mount the operation indicator (LED) in a clearly visible location. Avoid interference from ambient light shining into BCR’s
window. Avoid excessive dust on window. Avoid scratching window. Avoid subjecting the bar code reader to heavy vibration.
■
MAINTENANCE AND REPAIR
DANGER!
Never disassemble the reader. Users expose themselves to the risk
of laser radiation if they disassemble the device.
Do not attempt repairs or maintenance of the V550-A20. The V550-A20 contains no user serviceable parts. Refer all servicing to an
authorized Omron representative.
