Cleaning Plastic Window
The plastic window has been treated at the factory to
dissipate static charges. If cleaning is necessary use
cotton dipped in a solution of common household
detergent and water. After cleaning, allow the solu-
tion to dry without rubbing; the resultant detergent
film will effectively dissipate static charges.
CAUTION:
Solven
ts and liquids used in radio and TV shop work
may craze or scar the plastic window if applied to it.
