CAUTION Risk of damage to the handheld scanner. Do not submerge the scanner in water. The scanner's
housing is not water tight. Do not use abrasive wipers or tissues on the scan window: abrasive wipers may
scratch the window. Never use solvents (alcohol or acetone) on the housing or window: solvents can
damage the finish or the window.
Scanning performance can degrade if the scan window is not clean. If the scan window is
visibly dirty, or if the scanner is not scanning well, clean the scan window with a soft cloth or
tissue dampened with water (or a mild detergent-water solution). If a detergent solution is
used, rinse with a clean tissue dampened with water only.
The scanner housing can also be cleaned the same way.

Bar-Code Decoders. One decoder reads the cassette label, the other decoder reads the sample
label.
The instrument activates the bar-code reader while piercing a sample tube in Automatic
aspiration mode.
IMPORTANT
labels could prevent the instrument from reading the bar-code labels. Ensure the bar-code labels are
undamaged. Ensure the bar-code labels conform to the specifications provided in the online help.
The instrument reads both the tube and cassette labels. If the instrument cannot read the tube
label, the instrument only reports the cassette label.
