Maintenance
Your device provides reliable and efficient operation with a minimum of care. 
Although specific maintenance is not required, the following periodic checks 
ensure dependable operation:
Cleaning the Scanner
The scanner or base’s housing may be cleaned with a soft cloth or tissue damp-
ened with water (or a mild detergent-water solution.)  If a detergent solution is 
used, rinse with a clean tissue dampened with water only.
Cleaning the Window
Reading performance may degrade if the scanner’s window is not clean. If the win-
dow is visibly dirty, or if the scanner isn’t operating well, clean the window with one 
of the cleaning solutions listed for Health Care Housing, below.
Caution:   Do not submerge the scanner in water. The scanner’s housing is 
not watertight. Do not use abrasive wipes or tissues on the 
scanner’s window. Abrasive wipes may scratch the window. 
Never use solvents (e.g., acetone) on the housing or window. 
Solvents may damage the finish or the window.
