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 eye glasses worn by the user.
Radiant Energy The DLL2020-WO uses a low-power laser diode
operating at 650 nm in an opto-mechanical scanner
resulting in less than 0.7 mW peak output power.
Laser light observed at 15.0 cm (5.9 inch) 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 0.90
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 to make 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 performan-
ce of procedures other than those specified
herein may result in hazardous laser light
exposure.
