SERVICE GUIDE
Preface
Laser Safety
The Omnidirectional Laser Scan Module Scanner complies with safety standard IEC 60825 for a Class II laser
product. It also complies with CDRH as applicable to a Class IIa laser product. Avoid long term staring into direct
laser light.
Radiant Energy: The Miniature Dual-Laser Omnidirectional Hands-free Scanner uses two low-power visible laser
diodes operating at 650nm in an opto-mechanical scanner resulting in less than 3.9µW radiated power as observed
through a 7mm aperture and averaged over 10 seconds.
Do not attempt to remove the protective housing of the scanner, as unscanned laser light with a peak output up to
0.8mW would be accessible inside.
Laser Light Viewing: The scan window is the only aperture through which laser light may be observed from this
product. A failure of the scanner motor, while the laser diode continues to emit a laser beam, may cause emission
levels to exceed those for safe operation. The scanner has safeguards to prevent this occurrence. If, however, a
stationary laser beam is emitted, the failing scanner should be disconnected from its power source immediately.
Adjustments: Do not attempt any adjustments or alteration of this product. Do not remove the protective housing
of the scanner. There are no user-serviceable parts inside.
Caution: Use of controls or adjustments or performance of procedures other than those specified herein may result
in hazardous laser light exposure.
Optical: The use of optical instruments with this product will increase the eye hazard. Optical instruments include
binoculars, magnifying glasses, and microscopes but do not include normal eye glasses worn by the user.
For CE-Countries
This scanner is in conformity with CE standards. Please note that an approved, CE-marked power supply unit
should be used in order to maintain CE conformance.
This manual is in A4 format. Please check your printer setting before printing it out.
