Maintenance
Your device provides reliable and efficient operation with a minimum of care. 
Although specific maintenance is not required, the following sections describe 
periodic checks to ensure dependable operation.
Clean the Scanner
The scanner and scanner window may be cleaned with a soft cloth dampened with 
water or a mild detergent-water solution. If a mild detergent solution is used, wipe 
the scanner or base with a clean cloth dampened only with water to remove any 
detergent residue. 
Note: Reading performance may degrade if the scanner’s window is not clean. If the window 
is visibly dirty, or if the scanner isn’t operating well, clean the window. 
Caution:   Do not submerge the scanner in water or cleaning solution. 
Do not use abrasive wipes or cloths 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.
Caution:   Ensure all components are dry prior to mating the scanner with 
charging accessories or other peripheral devices. Mating wet 
components may cause damage not covered by the warranty.
