SCANTECH ID (Champtek company) Discovery SG-20 - Manual (Page 12)

Safety 4
English:
The DISCOVERY scanner complies with safety standard IEC 825-1 (1993) for a Class I laser
product. It also complies with U.S. 21CFR1040 as applicable to a Class IIa laser product. Avoid
long term viewing of direct laser light.
Optical:
The use of optical instruments with this product will increase eye hazard. Optical instruments
include binoculars, microscopes and magnifying glasses but do not include eyeglasses worn by the
user.
Radiant Energy:
The DISCOVERY uses a low-power laser diode operating at 630…670 nm in an opto-mechanical
scanner resulting in less than 0.7 mW peak output power. Laser light observed at 13 cm (5.1 in.)
above the window through a 7 mm (0.28 in.) aperture and averaged over 1000 seconds is less
than 3.9 µW per CDRH Class IIa specification. Do not attempt to remove the protective housing of
the scanner, as unscanned laser light with a peak output up to 0.9 mW could be accessible inside.
Laser Light Viewer:
The scanner window is the only aperture through which laser light may be observed on 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 to or alteration of this product. Do not remove the scanner’s
protective housing. 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.
