connecting it to telephone wires, light-
ning rods or gas pipes.
The power plug should be inserted
fully into the power outlet.
An unstable connection may cause a

where it might be exposed to
dust.
There is risk of fire.
Do not install the product in a place with
no ventilation (e.g., on a bookshelf or in a
closet) or on a carpet or cushion.

the increase in the internal temperature.
Ensure good ventilation around the
projector. The distance between
the projector and the wall should
be more than 30 cm.
Failure to do so may result in a fire due to
the increase in the internal temperature.
Do not use the projector in a damp
place such as a bathroom where it
is likely to get wet.
This may create a fire hazard or result in
electric shock.
