Lens and main unit cleaning
 WARNING
Request cleaning and maintenance of a ceiling-mounted unit from your sales 
representative.
 Attempting to clean or replace the lamp in a high location by yourself 
may cause you to fall, resulting in injury.
Lens cleaning
Clean the lens with a commercially available blower 
and/or lens cleaner.
The lens is easily scratched, so do not rub it with hard 
objects, or strike it.
Main unit cleaning
Unplug the power cord before cleaning the main unit.
Wipe dirt off the main unit gently with a soft cloth.
Do not wipe the main unit with a damp cloth. Doing 
so may allow water to get inside, resulting in an 
electric shock or unit failure.
Do not use benzene, thinner and the like as they 
may deform or discolor the unit or damage the paint 
surface.
Do not use a chemically saturated cloth.
