function (Page 48).
There is no factory preset for the password or the

case.
2Remove the inner padding from
the carrying case, and fold it in
the direction of the arrows.
3Reinsert the inner padding into
the carrying case.

•Be sure to insert the inner padding to
protect the lens and the projector.
4Place the projector and the ac-
cessories in the carrying case.
Info
•Be sure to attach the lens cap to pro-
tect the lens.
•Be sure the projector has cooled
down sufficiently before placing it in
the case.
Info
•This carrying case is only for storing and
carrying the projector.
•Sending the projector in the carrying case
as a parcel may cause damage to the pro-
jector. If you send the projector in the car-
rying case as a parcel, be sure to place it
in a sturdy case and with enough shock
absorbing material to avoid any damage.
•Do not expose the carrying case or projec-
tor to direct sunlight, near heat sources, or

Cleaning the lens

Use a commercially available blower or lens
cleaning paper (for glasses and camera lenses) for
cleaning the lens. Do not use any liquid type cleaning
agents, as they may wear off the coating film on the
surface of the lens.

As the surface of the lens can easily get damaged,
be sure not to scrape or hit the lens.
Cleaning the exhaust and intake vents

Use a vacuum cleaner to clean dust from the
exhaust vent and the intake vent.
Cleaning the projector

Be sure to unplug the power cord before cleaning
the projector.

The cabinet as well as the operation panel is made
of plastic. Avoid using benzene or thinner, as these
can damage the finish on the cabinet.

Do not use volatile agents such as insecticides on
the projector.
Do not attach rubber or plastic items to the projector
for a long time.
    The effects of some of the agents in the plastic may
cause damage to the quality or finish of the projector.

Wipe off dirt gently with a soft flannel cloth.

When the dirt is hard to remove, soak a cloth in a
mild detergent diluted with water, wring the cloth
well and then wipe the projector.
Strong cleaning detergents may discolor, warp or
damage the coating on the projector.
Make sure to test on a small, inconspicuous area
on the projector before use.
