Preparation — Precautions for use
ENGLISH - 21
f
Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of
the light source, or result in deformation of the projector due to heat, which may cause malfunctions.
Follow the operating environment temperature of the projector.
f
Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
r
Ask a qualified technician or your dealer for the installation work such as installing to
a ceiling.
To ensure projector performance and security, ask a qualified technician or your dealer when installing the
projector in a method other than the floor installation or when installing the projector in a high place.
r
Ask a qualified technician or your dealer to install the cable wiring for DIGITAL LINK
connection.
Image and sound may be disrupted if cable transmission characteristics cannot be obtained due to inadequate
installation.
r
The projector may not work properly due to strong radio wave from the broadcast
station or the radio.
If there is any facility or equipment which outputs strong radio waves near the installation location, install the
projector at a location sufficiently far from the source of the radio waves. Or, wrap the LAN cable connected to the
<DIGITAL LINK> terminal using a piece of metal foil or a metal pipe which is grounded at both ends.
r
Image adjustment after installation
Projected image of the projector is affected by the ambient temperature around the projector or the increased
internal temperature caused by the light from its light source, and it will be unstable especially right after the
projection has started.
This projector is equipped with the active focus optimizer function and automatically corrects the focus based
on the detected temperature change of the lens or the detected change in brightness of the image, enabling the
focus to be stable even just after switching on the power or when there is a large change in brightness of the
image.
For details of the active focus optimizer function, refer to the [PROJECTOR SETUP] menu

[ACTIVE
FOCUS OPTIMIZER] (

page 129). Operational specifications and factory default setting differ depending on
the projection lens.
When using the projector with the active focus optimizer function disabled, it is recommended to perform the focus
adjustment after 30 minutes or more have elapsed with the focus test pattern displayed.
For details of the test pattern, refer to “[TEST PATTERN] menu” (
x
page 155).
r
Do not install the projector at an altitude of 2 700 m (8 858') or higher above sea level.
r
Do not use the projector in a location where the ambient temperature exceeds 45 °C
(113 °F).
Using the projector in a location where the altitude is too high or the ambient temperature is too high may reduce
the life of the components or result in malfunctions.
Do not use the projector in a location where the ambient temperature exceeds 40 °C (104 °F) regardless of the
altitude when the optional Wireless Module (Model No.: AJ-WM50 Series) is attached to the projector.
r
Projection in all 360° direction is possible.
