diation from the device and to minimize external electromagnetic interference. However, equipment that is 
very susceptible to interference or that emits powerful electromagnetic waves could result in 
interference 
if placed nearby. If this occurs, place the 
 and the other device farther apart.
With any type of electronic device that uses digital control, including the  , electromagnetic interference 
could cause malfunction, corrupt or destroy data and result in other unexpected trouble. Always use caution.
Cleaning  Use a soft cloth to clean the panels of the unit if they become dirty. If necessary, use a damp cloth that has 
been wrung out well. Never use abrasive cleansers, wax or solvents, including alcohol, benzene and paint thinner.
