ATTENTION: Other than cleaning the scan window,
no user maintenance of the Reader is required. Do not
open the enclosure!
For optimum performance the scan window should be clean.

ATTENTION: Only use reagent grade alcohol to
clean the window. Do not use organic solvents. Do
not use abrasive materials, such as disposable paper
wipes to clean the scan window. Disposable wipes
usually contain glass fibers which will scratch and
cloud the window.
To clean the scan window:
1. Turn the Reader off.

ATTENTION: Do not attempt to clean the
window while the Reader is turned on. Although
momentary exposure to the laser light is not
harmful, precautions should be taken to avoid
looking into the beam.
2. Verify that the Module LED on the Reader is off.
3. Dust off the scan window and adjacent areas with clean air.
4. Clean the window using a reagent grade alcohol or a similar
cleaner for precision optics and lint free lens cleaning paper. To
avoid smearing and fingerprints, wipe the window in one
direction and then discard the tissue. Repeat as required.
Note: Clean the window in sections if the entire surface contains
contaminants.
5. Apply power to the Reader. The Module LED on the Reader
should be on.
