You should clean the projector if it becomes dirty or if the quality of
projected images starts to deteriorate.
Attention
Turn off the projector's power before cleaning.
Cleaning the Projector's Surface
Clean the projector's surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water containing
a small amount of neutral detergent, and then firmly wring the cloth dry
before using it to wipe the projector's surface.
Attention
Do not use volatile substances such as wax, alcohol, or thinner to clean the
projector's surface. The quality of the case may change or become discolored.
Cleaning the Projection Window
Use a commercially available cloth for cleaning glasses to gently wipe the
projection window.
Warning
Do not use sprays that contain flammable gas to remove dirt and dust from the
lens. The projector may catch fire because of the high temperature of the lamp
inside the projector.
Attention
Do not rub the lens with harsh materials or subject the lens to shocks, as it
can easily become damaged.
Cleaning the Obstacle Sensor
Clean the obstacle sensor when the message "Remove any obstacles that are
interfering with the projection area." is displayed along with a warning
sound. Use a commercially available cloth for cleaning glasses to gently
wipe the obstacle sensor.
Warning
Do not use sprays that contain flammable gas to remove dirt and dust from the
obstacle sensor. The projector may catch fire because of the high temperature
of the lamp inside the projector.
