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 Computer
The CK65 housing, scanner window, camera window and touch screen 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 computer with a clean cloth 
dampened only with water to remove any detergent residue.
Note: Always turn off the CK65 and leave the battery installed when you clean the 
computer. 
Note: Reading performance may degrade if the scanner window is not clean. If the window 
is visibly dirty, or if the scanner is not operating well, clean the window. 
Caution:   Do not submerge the computer in water or cleaning solution. 
Do not use abrasive wipes or cloths on the windows or touch 
screen. Abrasive wipes may scratch the windows and touch 
screen. Never use solvents (e.g., acetone) on the housing or 
window. Solvents may damage the computer finish, the 
windows or touch screen.
Caution:   Ensure all components are dry prior to mating the computer 
with charging accessories or other peripheral devices. Mating 
wet components may cause damage not covered by the 
warranty.
