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.
